LOL Noctiluca!

Yes, he actually spends most of the film whining about Aerith and Zack. I don't think he ever really talked about dying or even mentioned the kids at all. He just used the disease as an excuse to get away from Tifa and the children. Most of his actions in the film seem to be him dwelling on the idea that the two happiest people from FFVII hate him.

Its really apparent when he talks to Vincent and they have their conversation about forgiveness. I thought it was rather amusing that Cloud finally stopped moping around after getting advice from the other most emo character in the game and being talked down to by a child.

Maybe Cloud is depressed cause he has to star in a silly sequel?
