I love Brian for asking Em what his problem is. Even if he does give shitty advice.
Seriously though, WHY would you ever take relationship advice from Brian, of all people???
When you think about it, though, Brian's rules for commitment are odd. He's encourages Emmett to fuck Dijon and defends both Lindsay and Mel to themselves when they cheat, but then even when he and Justin are apart, he honors their no kissing rule. He's a strange man.
