How would the littles act by themselves?
Oooohhh okay I like this one!!! Thank you so much for this ask!! I've honest to god been STUMPED on all my asks recently but this one has managed to intrigue my silly, illogical, unfocused brain!!
Darry: He's rarely regressed - only ever does it every couple months, once his stress piles up enough that he can't hold back the regression. Usually, he makes sure he's alone before he regresses, so no one is ever really there anyways, other than sometimes Two-Bit who seems to have a sixth sense for when Darry needs someone to support him. Generally, he's pretty quiet. Doesn't make a lot of noise, doesn't really play with toys, none of that. He was always a more athletic, quiet kid, and that shows when he's regressed. Not to say that he doesn't or can't like being loud, and playing with toys, and never throws tantrums or has meltdowns! It's just that when he's alone, it's less fun to push toy cars back and forth, and there's no one to cry to when he's upset, and he's also influenced by his big mindset to not want anyone to know when he's regressed, so he tries to be quiet even when he wants to play loud games. Besides, usually his regression makes his physical aches and pains a lot more prominent, so he spends his time napping, or taking a bath, or something equally relaxing.
This isn't a part of the ask, but it's just an aspect of Darry's regression I'd like to yap about and can be skipped over if you want just the ask: Part of the reason Darry doesn't regress a lot is due to how grounded in reality he is. He's tried zoning out, repressing memories, forgetting his responsibilities so he can relax, and he even tried indulging (for lack of better words) his regression a couple times, but he just couldn't do it. He's too aware of everything. At all times, he can feel his broad shoulders and how they make his arms hang kinda awkwardly at his sides. Can feel when the sun is beating down on him at work, even when he tries his hardest to conjure up memories of winter. Can remember every moment where he wished he'd done something differently. Even when he tries just staring at a wall and getting lost in thought, his mind is analyzing every mark and dent in the wall at 1000 miles an hour. He's insufferably aware of everything, and always has been - even when he was a teen, out partying, and trying to ignore the clock so he can truthfully say he lost track of time and didn't mean to come home so late. It's why he's so frustrated by Pony's (and anyone's really) forgetfulness and thoughtlessness. The way his mind is always aware, and thinking, and observing, makes it impossible for Darry to let go of himself and relax and regress willingly. It always has to be involuntary. (based on my own experiences with escapism and regression)
Two-Bit: I've talked about this before, but people can't tell when he's regressed. He doesn't regress too young, and he's always been the 'comic relief'. The one laughing and joking and stumbling over nothing due to both clumsiness and alcoholism. He started drinking pretty early too, so even when he's regressed he's drinking and playing cards and cursing. The only sign he's regressed is that he drinks more, both because his regression gives him all these weird, twisted up feelings, and so he can excuse any slurred words, clumsiness, or childishness. All that to say, whether he's big and with someone, little and with someone, big and alone, or little and alone, he's gonna act the same, because even as he grows and changes, the happy mask he wears doesn't.
Dally: Cries. He cries. A lot. He's a baby regressor, with the oldest he gets being 5-6, and he hates being alone. He'll cry until someone comes for him. If no one does for hours and hours, his cries will quiet and he'll just quietly sob himself to sleep.
Steve: He's usually pretty quiet when he's without Sodapop but still has company. However, when he's without Soda and fully alone, he's surprisingly loud. As a kid, he liked taking advantage of the times his old man was out of the house to do whatever he wanted - eat the food his dad won't notice is gone, watch TV on full blast, make super loud special effect noises when playing with cars, etc - and he does the same when regressed. When he's alone, he can let himself be as loud or quiet as he wants without worrying about the consequences. Sometimes, of course, he prefers to be quiet when he's alone, but he kinda thinks of it as a wasted opportunity, since it's rare he's fully alone, and he can be quiet anytime, but he can't always be loud.
Soda: Loud. This boy is loud. It's rare he regresses, like super super rare, but if he's regressed and alone? He's looking for someone. He wants to play with his brothers, or dig in the dirt, or run up and down the streets of Tulsa until he collapses from exhaustion. The only thing stopping him from just going around on his own and finding something to do is the fact that the caregivers will scold him into next month for it. Sometimes, though, when he's not doing too hot, and he finds himself regressed and alone, he'll just find a corner and sit there. Usually in his and Pony's bedroom. It feels scary being alone, but he needs the time to decompress and think and regulate himself, and he'd rather be alone for that.
Johnny: Quiet constantly. Maybe he's crying softly in a corner because he's upset, or maybe he's completely fine and playing with a stick, but either way he's quiet - alone or otherwise.
Pony: Quiet. He's so constantly surrounded by loud people, and loud environments, and his thoughts are loud, so whenever he's alone it's like something shifts in his brain and he completely shuts down. Leave him alone for long enough and when you come back he'll be limp on the ground staring at nothing.
