We're Not Fighting

Jack knows he's a flirt. He's a hit with the ladies -- and men -- but it means nothing to him because he's with Aiden. They've been together in a committed relationship for years now, and in Jack's mind, no one else matters. So when a new girl in the office named Leslie flirts back, Jack thinks nothing of it.

Aiden, on the other hand, is pissed. 

The worse part is Jack won't tell Leslie he's with someone. He doesn't think he has to. Soon the tension between the two men starts to wear them down. Jack just wants the whole thing to blow over, but it looks like Aiden's about to blow up. 

When Jack finally says something to Leslie, will it be too late to satisfy Aiden?
