Hmmm, alright! Were you thinking like little habits a character has that only their partner ends up noticing or something they do together a lot? Stuff like that?

Cool! Well, Axel tends to chew on the inside of his cheek when he's nervous, and he'd be down to try pretty much anything with the other two... except maybe fighting, he's a bit fragile. XD Cuddles and movie night are a definite yes though. With Leroy, he gets kind of fidgity when he's upset, especially with his hands, and he'd probably like to lsten to Nabih rant about something random, not really because he wants to learn something, just because he thinks it's cute when his 'Nab' gets excited about something. Ethan mostly just gets extra jumpy when he's nervous, and he's willing to do anything as long as it makes TJ happy :)

Also, Leroy is totally clingy and ultra over-protective when he cares deeply about someone, he'd definitly ask Nabih for cuddles when he thinks they're alone.

Oh my gosh that is so cute!! Especially the Leroy stuff that just makes me smile-

As for Axel, Aries, and Cal, I can see them training and practicing together and Axel cheering the two on while they are fighting and them being mindful of Cal's asthma once he reluctantly tells them about it and Aries teaching them both defensive and not really harmful techniques and- There is so much wholesomeness with just one idea! >~<

Awww, that's so cute!!! I love it!
