Please Thanatos, where else would Tidus be going for kitchen necessities than the kitchen? And a transgate doesn't bother him - it even gives them a second where it needs to be set to the location. A perfect pause.

"That still sounds like some people should!" Tidus remarks. "You met the lady called Death? Plenty of dead...not dead people around too."

Waaait. Unless there's an actual real reason for the guy to say that, that isn't just to sound mysterious. "You're not slowly killing me right or something, are you? Like a...presence drain?"

'I'm deadly to be around'?
