Naruto Thread (Spoilers For Sure)

Whats the difference between biting her and holding up glowy hands?

Glowy hands = introduced way back in part 1 before it became essential. biting her introduced 2 panels before it's needed with no explanation whatsoever. If sasuke had said something like "Her healing power will be useful" or something when he first met her, to at least hint at it before it's needed. It gets even worse when he pulls new powers out that he doesn't even need. I'm looking at you, sasuke summoning a hawk for no apparent reason.
