Hah, the joke is on Tidus, because Inigo will be able to fight even without rest! Witness the magical power of having adjusted your body so much that you can fight for days on end if you have to.. until your body just shuts down entirely and you collapse and don't wake up for a good while. But look, that's clearly just a small detail...

Not to mention that the other has thankfully already changed the subject. The question just makes Inigo shrug slightly though.

"It depends." Usually he would have been a bit more decisive with his answer, but the fact that one of his favourite people on the train - NO, NOT YOU, TIDUS - is more or less permanently helping out blue now sways him a bit. "I'll probably be sticking with purple. It seems like blue has enough going for them to not need the extra help. I mean, you did see that huge lion thing, right?"
