I don't think he was an asshole either. Honestly, he was what, a 22 year old guy? If you know any 22 year old males, you know they aren't necessarily the most mature or best with words. I think he had a lot being presented to him, and wasn't sure how to handle the situation.

I'm going to assume Lance isn't going to lie about how this went down, seeing as he is still friends with Justin. So that being said, I think Justin handled it very poorly if that was the extent of it. Again, we don't know the rest of that story, so I'm going to wait until the book gets here to decide if Justin deserves to be smacked upside the head for what happened and how he dealt with it.
