Yes. I'll be in the Avatar State. None of the others have said they need to touch a specific place on me yet, so I don't think they need something as exact as you do. But even if something is a little off, Raava will be watching. She'll be able to figure it out. She hasn't done anything like this before, but she's always been able to adapt to this sort of thing quickly. The first time she passed through me to exchange the power of the elements was the first time anything like that had ever been attempted. She did just fine.
