#kinda sorta...

They all care for each other. Flippity flip flips. This kinda just seems right to me, as they'd be protective of each other, sticking together through thick and thin...

...so if you act as a CG for any of them, the others will be around to help you as they're more than likely the typical primary CGs for each other... they're a bit codependent in this way, tbh...

Loz is the least obvious about when he's regressed, surprisingly, because there's a lot of overlap between how he usually acts and how he acts when regressed. Honestly, I could see him being a permaregressor? Not fully sure on that one. I see him as easily able to slip in and out of it but not really in control of it. He behaves how you'd expect but he really likes being doted upon. Probably the one to regress the furthest. He's pretty easy to care for outside of when he gets fussy. Fond of any sort of toys, Very babyre to me. Bonk cars into each other with him. Make nyooom sounds with the toys. EVERYTHING IN THE SQUARE HOLE! Building blocks and knocking them down. Busting a move. All of it. Very down with gross motor play.

Yazoo is interesting because I think when he's regressed he gets even more quiet, but instead of it being sourced from awkwardness, it stems from insecurity. All of the Remnants have some mental aches and pains and bad feelings from just... generally being Of Sephiroth and probably being fully capable of having the same humanity debacles he did. Yazoo, I think, would have regression that taps into any feelings of inferiority or not being good enough from Sephiroth's early experiment days, but he can't quite pinpoint them as such. He filters most of his wants through Kadaj or Loz, preferring to cling to them rather than anyone else... saying he doesn't try to be alone the whole time and just supress it. It's an act of vulnerability he doesn't often want to show. Prone to just masking it. Fond of quiet play and storytime. Give him one of those marble maze balls. Or maybe he'd like a dollhouse to play out a gentle life.

Kadaj is a stubborn, stubborn regressor. He wants control, he wants to be a big kid, he wants to do it by himself ONLY. Sometimes his brothers get through to him by letting him play the Leadership card and letting him "organize" them to help him do as he requests. He hates not having any control, feeling unsure of things, and I don't think he even likes regressing initially. Kadaj is the most difficult to deal with. He doesn't want to play. He wants to outright fight you. Sometimes he's harder to handle when tired, but once he's really, really sleepy, he's more compliant. Maybe as time passes, he'd get better, though. Getting him to work with you and not against you is probably the most satisfying feeling. He likes to be rewarded.

All of them occasionally yearn for their mother. They have different ideals of her though. Loz wants to play with her, Yazoo wants to be held by her, and Kadaj wants her praise and approval. Yet all three are oddly a bit disappointed by the reality.

As carers for one another, Kadaj is pretty in-tune with his brothers, so it's easy for him to take charge with either Loz or Yazoo. Yazoo is very gentle and tends to give Kadaj space or just watch Loz play and is especially good at calming Loz down or tactically going with Kadaj's... Kadajenings. Loz is good at getting Yazoo out of his shell and sometimes he's struck gold in entirely distracting Kadaj from whatever he was mad about to something he can actually do.

As carers for others, Loz is somehow the best of the bunch yet prone to accidentally regressing alongside a regressor, going up and down and in and out of regression. Yazoo is very lowkey and content with parallel play-type activities, good for a regressor who isn't very needy. And Kadaj... he tries to take charge but he's less attuned, which throws him off and sometimes frustrates him.
