Hmm. Sam makes me sad. I see myself in him quite a bit though. The way he has a hard time actually making friends is a biggy. He is awkward, and he is well aware that no one wants to hear about his current obsession, but he longs to connect with someone. He is also very unsure about himself and a little paranoid. All things that I totally get.
He is a really good grounded character to identify with in this world he is thrust into of alien hottie superheroes.
