Something I still like about the boys' dynamics is that on the one hand you have Edwin, self professedly allergic to emotions, who will nevertheless make most inconveniences in his life everyone else's problem (at least if the way he handles Crystal's arrival is any indication)
Vs Charles 'I like emotions. Big emotions guy, me' who will manage everyone's issues before he admits that he even has any of his own
This works great with their everything, too: Edwin, invisible and quiet all his life, now taking up all the space he wants vs Charles, under constant scrutiny for 16 years, seeking the safety of being unperceived
Idk, I was reminded of that while reading a fic and I really like it
This is also the reason why I personally think if either of them is going to start off an explicit discussion of consent and stuff when it comes to intimacy, it's definitely Edwin
