I thought it was incredible!
And the shot of Walter placing the Walking Liberty half-dollar coin on the grave of his “real” son Peter Bishop, who died as a boy, gave me chills.
Who is the man posing as Peter? What a great episode.
The man posing as Peter is.....Peter. Walter had mentioned earlier that he had lost something that was dear to him and that he had crossed over to the other side and recovered what was lost. "Our side" Peter died when he was 7 while "Other side" Peter was living in an alternate universe. What Walter had done was to cross over and take the alternate Peter and bring him back to "our" side. Headache anyone??
