Ah, so hank screwed Kevin and felt guily, or while in the moment hank shouted Chase's name and Kevin became the little bitch we all knew he was! Dawson is right though Chase should not give up, it's clear that Hank isn't entirely over chase. But now Hank is the cheater! He seriously needs mental help.
The only thing I don't understand is why Chase didn't tell hank that Dawson is actually seeing someone else. The only reason I see for him to do that is to further Hank's own jealousy and that's not a healthy thing to do..
I'm also secretly hoping hank goes after chase.
