Of course!! :P

YIN:
* I feel like he always regresses a bit younger than Yang does, usually around 2-5.
* He usually regresses in generally tense situations, or if there's even just a slight trigger.
* He's the type to hide behind someone almost always, or holding someone's hand.
* Yet, he's very sweet and kind, usually open to talking to many others when regressed. He just likes the extra physical support.
* He has a small stutter when he speaks, which is only noticeable if you're really close to him.

YANG:
* Usually regresses slightly older than Yin, usually around 3-6. He likes to brag about being older quite a lot.
* He usually regresses due to his own thoughts spiraling to the point he goes into littlespace.
* He's very reckless and carefree, causing a lot of trouble for others. This usually varies from small pranks to even bigger schemes.
* He has a habit of trying to bite people.
* He also has a stutter, but it's a lot more noticeable. He hates it.

• They both find comfort in Riggity Rex, though Yin's connection to Riggity is more apparent than Yangs.
