in my opinion, he was in the wrong. alex or alec? idk. the long haired guy, has NO right. he can have feelings, yes. he helped. but he is not his significant other. once he showed up to take care of him, his need was over. he obviously thanked him for taking care of hen. he's not stupid. but once he was there, alex needed to stop. they aren't in a relationship. his responsibilities ended once he got there. being possessive and aggressive over hen is something he shouldn't be doing.
All valid points but I stand by what I say Alec is allowed to care he is allowed to help he knew that hen liked hen from the get-go and he began to develop feelings for him
he's never tried to really intrude on their in a relationship as far as in the physical since they established themselves as a couple. As I've said all valid points

"What right do you have to feel that way?"
Cut Alex some slack he tried to help, no he DID help and he cares about hen that's "what right he has to feel that way"
Jeez Ivan don't get in your feelings.
don't let your insecurities get to you HEN is yours deal with it.
I understand that you want the cure for him so that you don't burden him or put him in danger and unnecessary situations like today but
you just have to realize you can't be everywhere at once and as uncomfortable as it is for you,
You need to see the big picture HEN was in trouble AND PAIN he needed help Alec helped end of story....you are gonna have to take one for the team and charge it to the game my guy ┑( ̄Д  ̄)┍
