I thought it might be Wes only because the actor is British in real life. Actors from the UK a funny lot compared to actors in the US. They don't like to do any one role too long. Dan Stevens in Downton Abbey a perfect example. He left after 2-3 seasons when he could have enjoyed the role much longer. The actor is on Jimmy Kimmel tonight, so I guess we will get the scoop shortly. So glad Nate and Frank are safe!
