CRIESSSSS I LOVE THIS QUESTION SM THANK YOU LIN!!!! ill start with the hanzo headcanon first because ueeee HE IS DEFINITELY A PLANT DAD!!!!! I'm not good with botany but he love love loves plants and has like. A legion of plants in our balcony HEBFNSJJSJS he thinks fake plants are the most disgraceful thing humanity has created

SO let's go with the reassurance qwq I'll start w Goro then Hanzo then Gale

Goro is... not very good at reassuring people. He didn't have a huge support system growing up (neither he or Hanzo did at least), and the people who were his friends tried to use her in one way or another. They don't know how to reassure people genuinely, because all she's used to is reassuring people with fake words that mean nothing... and he doesn't want to do that to me. Because they can empathize with my plight, and she wants to take care of me. He just... doesn't know how. So as a result, she turns to the Phantom Thieves and asks them how they comfort others. He takes down what they say into notes, and figures out what he'd do to help me. She tries what he's thought one by one, until she finds what works. They don't really like touching me unless I specifically ask for it, nor does she like only offering words. Instead, he's more hands-on in a sense that she makes me (bad) food, or offers to play video games with me, or offers to sit in silence with me, or does things for me like the chores in the house so I wouldn't feel too stressed about it. They get me my meds, call my doctors/psychiatrists for me, drive us around the city with no destination in mind just to get out of the house... she does many many different things for me that isn't the conventional way to reassure me and all of it means a lot to me ;__;

Hanzo is a little bit better than Goro at reassurance, but that's just because with OW Fuyu, he's had more experience with me over the years as my bodyguard. He's seen how much my environment affects me, or how my mental health affects me and has learned what to do. He usually pulls me into a hug and plays with my hair, whispering sweet nothings into my ears and attempts to reassure with words. But he's not so good with words, he just ends up threatening the people who did this to me, and swearing that he will shoot them down. But it's a comforting hug, and we sit like that in silence. He wipes away my tears and when we're done, gets me a glass of water and cooks me food. He carries me to our bed so I could rest, gives me my controller/laptop so I could play video games. He doesn't dare offer to play as he knows how bad he is at games, but he does spark conversation and prompts me to speak about the games I'm playing

Of the three, Gale is probably the best at reassurance. He grew up with a support system, although not too good, but he was in a space where he could give genuine care for people who wanted his opinion, without using him. And as a scholar and archmage, Gale has studied a myriad of things, mental health included. Of course, he doesn't know everything, and of the three, he's the least experienced with me and has known me the least amount of time in our respective timelines. So while he knows what's up, he doesn't know what applies for me and what doesn't just yet. So he asks. He tries to understand, does more research, observes. He's a man of logic first and foremost, but he tries to fix problems he sees to an obsessive degree. So whenever I'm down, he tries to fix it asap, and continues working on it so that I could be happier again. He offers words of advice, not affirmation, but when I ask for validation, he gives it. He cooks for me too, and definitely holds me if I need him to. He reads to me, casts spells for me, and even crafts small magical artifacts for me so I would have a trinket to fidget with. He's sort of like a mix of what Hanzo and Goro would do, just thrown in with a LOT of research as that's what he would do. But he definitely knows the right words to say of the three, and he means all of it

PHEW that was a bit to write qwq they're all very similar in how they give reassurance because, well, I seem to have a type 😭 they're all similar to one another in their own ways while maintaining some sort of individuality, which is why their responses while similar, are still quite different. I'm just happy to have such kind, patient, considering and loving s/os 🥹 they mean the world to me
