Subaru's dead pretty much. He's like a living corpse.

Ah, aren't we all? ^_~ Wasn't he actually kind of happy and nice at the end? I mean, he hauled his sorry, lazy, apathetic ass to save Kamui so...>_> Um...yeah, maybe he got over Seishirou's death or something.

...or he just started looking on the bright side of life ~~
