You have a great memory anon, something does indeed happen between them as teens :3c I'll keep the details to myself but Gary ends up in locked-in syndrome. Mikael is the first person to notice that Gary is aware and not merely comatose, which thankfully does lead to him getting the appropriate therapy and recovering some motor functions as he reaches adulthood.
At first it's complicated for Mikael to visit him but Gary's mother eventually helps and he gets to come and go as if family. In a way she kind of accepts him into the family too even if he's so outside of their circle. Mikael takes care of Gary when he's there and continues to do so even after he's discharged.

Their relationship becomes complicated, there's lots of resentment from Gary and at the same time Mikael remains his only means of escapism. Slightly sci-fi but these characters were first created within the context of being able to venture into other people's dreams thanks to an experimental drug and I still like this idea,,, experimental dream therapy designed to help coma victims, the last place where Gary can still walk and talk and taunt Mikael's guilt, always taking the form of himself as a child even as they grow older, the return to reality always hitting like a brick. Lots of fun but purely hypothetical, for now I'm having fun daydreaming about their teen years before the accident

Somebody asked for some over on tumblr so I'll give you the same facts I did over there !

(cw: self-harm, attempted suicide)

When they are together, Mikael is almost always touching Gary in some way: leaning on him, holding his arm, hand resting on his nape, keeping him close and corporeal. He'll sit behind him and hug him and casually hang his arms around his neck. Gary pretends to only tolerate it.

Their fights can get pretty nasty. Biting, scratching, hair pulling, nothing is off limits, but they mostly wrestle and roll on the floor until one of the two manages to pull free and punch/kick. Sometimes they'll start laughing with a split lip and a bleeding nose midway as if just play fighting, though usually it's mostly Mikael laughing and Gary trying to kill him for good.

Other times it devolves into other physical contact. Their hormones are in full bloom and there's only one step between anger and hunger when you're already touching and grabbing at the other anyway.
The contrary also happens, mostly because Gary is quick to anger and Mikael too stupid for his own good.

They're not always fighting though. Sometimes the dust settles and they've tired their bodies with whatever shenanigans kept them occupied so they'll slip into tender lazyness, lying together intertwined as close as possible, hands under shirts or playing with hair, breathing as one. It's the only way Mikael will keep calm for more than five minutes.

They often will try to sneak out of doing their chores to hang out away from the eyes of the adults. In the attic, up on the taller trees, on the roof or in the multiple nooks, crannies and hidden doors of the old house.

Mikael sometimes looks for unfinished cigarettes inside the ashtrays the staff hide when they're done smoking behind the kitchens; they try to smoke them nonchalantly, passing the small butt to each other, just enough for a disgusting taste of adulthood. Gary often gets sick from it so they don't do it often.

Mikael has tried LSD (directly) and weed (second hand) before; the only drug Gary has ever taken were the few grains of cocaine left on his father's desk, but it wasn't even enough to get a taste.

Despite Mikael busying his mind away from bad thoughts, Gary will sometimes isolate when depression overwhelms him. It becomes a game of hide and seek where Mikael will usually find him with fresh cuts, or sometimes worse. Thwarting Gary's suicide attempts has become a game ever since the first time he did it, though Mikael never laugh at it, even if he sometimes smiles still and says dumb shit after getting him out of harm's way.

I talked a little bit about it's anatomy before here but besides that, I think it has both an exoskeleton and an endoskeleton. Pretty much everything that is on the back is hard shell and everything on the front (including arms) is soft and has bones inside (at least for now, I'm still fine tuning it's design so it's subject to change).

Like a centipede it's organs are scattered along the body. The usual we share even with insects (brain, heart, gut, etc) and the glands found in centipedes, as well as tracheal lungs (the spiracles in his head are located where his 'nose' is instead of laterally on the other segments of his body) instead of human lungs. He /is/ venomous too, that's how he paralyzes his preys before eating them. He does have a tongue but it's used to move food, he tastes with his antennae :3c

As for... Intimate anatomy, he's got gonopods, which are modified legs (or here, arms) that are used to deliver sperm into the female. They are much more on the insectoid side, as the arms at the end of his body tend to look. They won't feature a lot in the comic because why use your dick-like appendage when you got so many hands to finger with ? ( ͡° ͜ʖ ͡°)

Hope this satisfies your curiosity ! It's fun to think about monster anatomy :3c

Mentioned before but Brownie is from an accidental litter of mutts; they were kept aside from the purebred puppies but he got to grow up around his siblings until he was around ten.

After that he was rarely socialized with other hybrids because he would mostly stay at home and wait for his owner. He was happy tho ! It was all he knew of the world for a long time but it did make him afraid of the unknown.

He used to be pretty small until he hit a second growth spurt a little late into puberty. Now he's rather tall and gangly but he try to make himself smaller by slouching.

He tries to be cute a lot because it used to get him praises and rewards. Sadly as he became older it started to irk his owner more and more :( he still has the habit ingrained tho

Before they left him at the shelter, his owner kind of neglected him, hence why he's all scruffy and unshaven.

He used to get all pampered and dressed in clean clothes every day when he was a puppy boy, now he only has a couple of old loungewear (he didn't mind, it smelled like his owner at first after all)

He misses his owner greatly and doesn't understand why he's at the shelter. He hopes they will come pick him up eventually and waits at the fence during outside time.

His favorite treat is cereal milk: his owner would always leave a little bit at the bottom of the bowl for him.

Of course, I love Jesse (⸝⸝ᵕᴗᵕ⸝⸝)

Jesse watches anime, mostly what's brought to the west then in the very 90s-2000s but he does end up seeking some fansubbed VCR tapes too. He enjoys classic magical girls shows with a bit of the classics from the streak of turn of the millenium cyber pessimism (he definitely smoked both the NGE anime and Serial Experiments Lain). Of course, he got introduced to hentai by La Blue Girl and the uncensored version of Kite, which doesn't have a lot to enjoy for him besides the torture of female characters (he's lovely yeah). He also likes the 70s Devilman anime, but his favorite part of japanese media is the mascot characters.

He was into the idea of puppy play but Domen kind of killed that for him. Let's say he liked to kick the dog and lock it in the crate for way too long. He still kinda yearns for a boyfriend who wouldn't find it cringe (but he's also persuaded no one will ever want him again so. Yeahh)

He's worked a few different fast food jobs, all shit. He stopped school as soon as possible because he always got recklessly bullied everywhere he went and he's had such shitty bosses that no one can vouch for him so he could get something better. Ange encourages him to apply to volunteer at different places to enhance his resume after being depressed at Ismaele's for a while and he ends up doing some at the shelter. The animals are cool but he's got very little patience left to deal with people so now he does cleaning/maintenance work (and a little socialisation in the kennels that are off limits for visitors).

He was into fashion but Domen also killed that for him. He'd tell him he looked ridiculous but then would still insist he should 'dress how he wants', sometimes even pushing him to do so knowing very well he'd now feel self-conscious dressed like that. He floated between emo, scene and visual kei with some skater influence in there.

He is sex-repulsed by women, which makes him the only true misogynist (it's actually trauma)(he's still incredibly misogynistic)

Though he had been relentlessly called a faggot as a teen, he didn't really think about the possibility of being gay before Domen confessed to him. If it wasn't for the trauma, he might be bi, so his attraction is genuine and not just fueled by hating women.

Sure ! Viorel is also one of my favorite ♡( ◡‿◡ )

Said previously, but he was the only boy from the orphanage survivors to be adopted. To this day, he's still uncomfortable calling his adoptive parents mom and dad, but they're understanding about it.

He loves them lots and they did their best to provide all he needed to heal from the trauma but they can be quite overbearing at time. They struggle to let him do things on his own and be independent.

He has tried prosthetics as a teen but he found them painful and too hard to get used to so he gave up on it. He's happy with his wheelchair, especially since it's a pretty good, modern one.

He had bed-wetting issues long into his teens because he had recurring nightmares of the event. It starts again after meeting with Cain as an adult but subsides as time goes on.

He loves kids but can't see himself becoming a parent because he fears the idea of dying and leaving an orphan behind. That's why he wants to become an adult any child can rely on, but who is still replaceable; that's how he sees it at least.

His adoptive parents weren't too sure it was good for him to stay in contact with Eli, but his then therapist encouraged them to allow and nurture this relationship so they could help each other overcome the traumatic events they experienced. They did their best to do it but still find Eli very difficult to read/interact with.

He always liked to borrow Eli clothes; the reasons just became different with puberty.

He hasn't come out as bisexual to his adoptive parents yet but. They kinda suspect he is some flavor of queer and are supportive of it. Funnily enough, the only people he has told is Eli and Ange (who is the only person he can talk about his feelings on the matter in depth).

Lesley: he works in a fish plant at night so... When he gets off work he smells like cold fish and rubber (because of his gloves and apron), but then he also takes care of his garden so it's dampened by the smell of soil. He also has a huge dog so there's a bit of that and occasionally lingering weed. He still uses the same shower products and laundry detergent as his grandparents did so when he's clean he has quite an old fashioned scent but it's usually quickly covered by the rest.

Elov: boysweat and adrenaline, random perfumes he puts on when going through the perfume isle of malls (he likes to put it in the crook of his neck so you'll smell it only when close there), a knack for the spicy and hypotonic ones but sometimes feeling like the fruity sickly sweet scent for adolescent girls. Lingering thrift store smell from his clothes mingling with coppery tints when crimson is still hiding under the sleeves. He borrows the scent of whichever bathroom he uses, motel and stranger shampoos, everchanging.

Wallace: he likes products who's perfume don't linger on him; he almost smells like nothing because of it, just clean skin and hair, even his deodorant and laundry detergents are unscented. His hand cream does leave a faint neutral creamy scent on him. Though since he started cooking more after getting out he does sometimes smells faintly of warm notes of thai spices and freshly brewed coffee. Elov likes him best sweaty, tasting of salt, cum and blood, he calls it his true scent.

Lesley: low monotone mumbles, the muffling makes it sound deeper than it is but it stays in the middle register. Has a scottish accent but sleepy, can make it harder to understand on top of it all since he really eats his words. Tends to croak when he has to speak up, but even then it quickly goes down in volume. Trails off if he has to speak more than a few words.

Elov: It's playfully seductive but drips with mockery. He learned very young that speaking into this slow, sultry tone of voice gets him things so now it's just conditioned into him. It's deep but like female deep, still the one with the highest voice of the three. Cute swedish accent when speaking english.

Wallace: friendly and calm, the tone of an old family friend you can trust. It doesn't sound unnatural /now/ but it used to take much more out of him to fake it. Slightly higher than his natural tone but still in the medium register, think how customer service voices tend to have that little extra lilt in them. Slightly faggoty some would say. His unmasked, natural voice is much flatter, dropping in pitch and staying there. It has been described as cold and even biting, not in an arrogant kind of way but like a stab. It's now tainted with the tiredness of middle age. He has no particular accent until he is in Scottish company, which suddenly makes it come out of the wood.

Lesley isn't quite good with other people when he doesn't have the goal to kill them in the end in mind, he hardly talks and avoids contact so it would be quite hard to get him out of his shell. Man just wants to go back to his rats, dog, garden and computer after work ! Though if you like any of those and aren't too hyper around him that could be a good angle to start with.

Elov managed by being ambiguously suicidal enough to confuse Lesley into letting him live long enough to brute force himself into a "relationship" (but you have to be brash enough and well, kind of dangerous enough to survive the first attempt) and Wallace wormed his way in by being forced in Lesley's care and moping around enough that even Lesley would offer to share time together to stop it (that's complicated because you'd need a twink with enough charisma and leverage to convince Lesley not to kill you)

So hum. You'd need a loooooot of time and patience and a knack for rodents and/or early personal computers. Good luck !
