Nemu dead? I don't think they'd kill her off, I think she'd make a cameo, like maybe the others...but then again, she had a weak constitution, so...but nahhh...I doubt it.
I dunno how come Sakura's still the same. How long did the tree stay dead post DC (or DCPC, or DCSG, or DCSS, or whatever
)? How did it come back?
