Hello!!! This is such a good thing to think about i love their little family... (I am also assuming the hoh is for house of the hearth akjdkfmhf i am so sorry if not, ALSO SORRY I WROTE A LOT)

I think the obvious one to start with is how well the other two know Lyney beyond his persona - they know where the cracks will start to show, they can read through the energy to pinpoint the moment it's too much. Even though of course he thinks they can't - and there are definitely things they don't know, putting himself through hell so they don't have to - and they'll let him push himself to some extent before they step in, just to keep him from putting distance between them.

For Lynette and Freminet it's almost the opposite, it's all about noticing when they CAN push themselves more but they're too reserved to do so, whilst also maintaining that safety around them, letting them know it's okay to be shy (more so for freminet), or to just prefer keeping to yourself, but that putting yourself out there is also important at times - just think of all the people they'd never have met if they didn't. I think, as siblings, they can truly bring out the best in one another and they work so well together, too. I think that'd be the main way they show they care, with little consistent acts that just read as support, without question, they're just always there.

Freminet is of course spoiled by the older two, though he tries not to be, that's their baby brother 😤 I think they'd argue over things like that though too. Freminet's insecurities probably make him feel as if he's not on level footing with the twins, and their desperation to make him think differently would cause some slight friction at times, like overcompensating leading to a little explosion of tension. It never lasts too long though! I like to imagine after the things they've been through they can be surprisingly good at communicating when it's about things pertaining only to the 3 of them.

They'd also fight over silly things, like siblings do - Freminet probably hates things being moved from where he had them, his routine being put off-kilter; Lyney totally takes up too much of the couch AND the blankets, and even though he's so put together he's always leaving things on the floor, or where they shouldn't be; Lynette can't stand loud noises all day and night, and not to mention how many times I'm sure the other two have eaten her last bit of dessert, accidentally and on purpose (brothers am i right).

Dynamic wise I love the idea that they're just, incredibly close all around. I feel like there is a lack (in game and out) of them as a trio sometimes, or it doesn't go quite as in depth as I'd like. I really just love the aspect of the twins seeing Freminet as the third one of their little set without question, and Fremi has two older siblings who would blatantly do anything for him. The twins are of course almost oddly in tune, but after so long with them it's impressive how on their frequency Freminet is, too.

I also think Lyney is blanket patrol at home, despite how he keeps it all it to himself when he's awake. Lynette and Freminet fall asleep anywhere except their beds because Lynette loves to nap and Freminet never manages to sleep normally with his anxiety, so Lyney always makes sure they're tucked up all toasty and warm to make the most of it.

I ALSO just KNOOOW they're all accidentally bringing home the same cake or tea, ending up with three of everything because they knew the other two would like it. They're stacked with little treats because of it lmao. It makes me sad to think of their past but so happy to know the three of them have each other no matter what, I JUST LOVE THEM !!!
