Yeah but who's face is it? My initial thought as to why Danzou couldn't absorb Sasuke's arrow was because his shoulder was his weakspot, which could imply that the face is actually the real Danzou. However, since it turned out the urgency was due to Danzou not being able to form seals, I'm going to just assume this isn't the case.

So... I dunno....maybe it's the 1st Hokage?
