I liked X, the weird little bugger he was, but I hope to hell they don't do a "rescue and redemption and now he's suddenly a nice guy" for Six schtick. I'd rather he stay the kid who grinds people up and puts their remains in boxes.
Also, now that we know X was originally a girl, should I refer to it as she? I mean, she or he takes a male form now, so, I dunno. Goddamn confusing shapeshifters.
