At the end of episode 1, Klein tells Kirito that he looked cute, and was totally his type (script):
You were actually pretty cute.
That's my type.
Does this mean something different in Japanese? Was something lost in translation? Or is Klein gay for Kirito? Or is Klein gay in general? I can't recall another anime that I've watched that had similar dialogue, but I don't watch anime where dudes are explicitly hot for each other either.
I'm re-watching SAO and I never noticed this the first two times through.
