Nick walks in, and Eric goes to see what he wants. They exchange some pretty harsh words, and Nick throws a punch. They start to fight, and Ryan runs out, pulling Eric away from Nick. He keeps one hand on Eric the whole time, repeating his name over and over, telling him to calm down. Nick and Eric have another small exchange, Eric tells Nick "if you want to continue this, you know where to find me", and Ryan tells Nick to get lost. Nick walks away, and the scene ends.
That's pretty much it. The scene cut right after that, so I don't know if they talked about it after that or not. Ryan didn't really have time to be too jealous then(or at least to show it). *shrug* Really need some screencaps! Don't know if the spoiler code was necessary or not.
