Re: SPOILER *all five books* THREAD FOR Game of Thrones (TV series discussion)
I think his name is Pate...the Alchemist aka Jaqen H'ghar kills him in Feast. Pate is in the epilogue so it's presumed the Alchemist took his identity and is a Faceless Man. It's thought to be Jaqen because of the Alchemist's facial description. It matches that of the face Jaqen took when he parted ways with Arya. Varamyr Sixskins is the only one alive I think, but he's in his wolf. His body was killed.
