Xion: Pretty gosh darn sick because heart collecting and doing of bad things and unconsciously stealing Sora's memories and keeping him comatose and then making BFF fight her until she died... yes guilty feelings there. Lots of them. Sick as a dog and probably getting hospitalised at some point.

Ichigo: God with his mother issues? And various other issues where shit happened because he couldn't get his head out of his ass/was actually a big ol' bucket of rampaging monsterness? Shounen derp in a coma at some point, I think. >3
