I agree with Bidoof, that definitely was NOT the faceless man dying.
The think I wanted to bring up was from the day post. With Bran dying, Bard said that Ned would learn Sansa and Arya's identities. Similarly, his last vision showed him "Sonata, Shak, Ice, Charlie Brown, Nakuzami" and that 2 of them are Starks, and the rest are others. Taking Robb into account, Ned should know at least 1 of these 5 listed. If Ned could verify, we will have a 75% chance of getting an other in a lynch today.
