Whaaaaat? Everything Ghirahim cooks is fabulous! Granted, it is probably not edible by normal humans. For the life of me I cannot figure out who the guy is peeking through the window in that picture. O_O
@Shy Guy, it isn't so much a theory, but simply seeing as how it wouldn't make sense for Ghirahim to die in Demise's fight. He was a blade, and he wasn't sustaining any damage in the fight, and Demise wasn't killed, but merely weakened enough to be sealed all over again, which obviously wouldn't kill Ghirahim, or else Ghirahim wouldn't have been alive throughout Skyward Sword. Probably couldn't count the number of times I've expressed this in these forums.
Also, I think the Zelda creator(s) commented on Ghirahim not being related to Vaati. Could be wrong, but I think I remember reading that somewhere.
