[Phylum]

This is one of the weird things in the show really. In the book I felt like the faceless men had to be anybody, not nobody. I always thought that wearing a face was about just becoming somebody, not the specific person whose face it was. The lying game was very different - it wasn't all about Arya not being Arya, it was about Arya being able to lie and pick a liar. I guess they had to externalize her conflict more.

This is really making me rethink all of the stuff in the book about the waif's past though.

Mind you apparently I misunderstood the prologue to AFFC when I read it, so apparently in the book there is actually a case of someone being "replaced" by a faceless man wearing their face.

Oh and I read a really good theory about Lady Crane, Arya and the waif which is similar to what's suggested in that video, but also proposed that Arya might not be going back to Westeros from here. The faceless men might need her in the east...
