I'm addicted to Brian, so I was always pulling for Justin to go back, but I totally think Ethan was necessary and yeah, tragic.

And he got shafted in the end, over any excuse to go back to Brian. Which, I mean, didn't make cheating any less of a stupid thing to do, but I don't think that was really why Jusitn left. I mean, man, who lives up to Brian Kinney? :)
