Justin was jealous when the float committee liked Raja's idea better than his. So he comes up with an outrageous idea for another float which they all like but ends up getting them in trouble. Do you think we'll see more of this jealousy throughout the season?

I wouldn't be surprised. Justin wants people to like him so badly that he will be threatened by any signs that people might like Raja better. Also, one of the reasons that Justin feels connected to Raja is that he sees Raja as another unpopular person. If that changes, it could feel threatening to Justin.

I agree, the jealousy will probably come up again. It would make for some more interesting episodes.

I agree as well.

And if this does happen again, I'm sure Justin will realize he's wrong and will apologize to Raj. They're good friends.

Yes, I'm sure he will. He always feels bad when he doesn't treat Raja well.
