I totally missed this during the show, but people online here, there and also here are saying that the man Hurley saw in the chair in Jacob’s cabin sure looked a lot like Jack’s dad, Christian Shepard (played by John Terry). Makes sense, since it sure seemed Jack thought his dad was still alive in the season-finale flash-forward. Besides, the father’s coffin was empty on the island. So I guess he’s one of of Hurley’s “Oceanic Six”! Now, otherwise I don’t recall seeing him in a single scene. So isn’t it odd that imdb.com lists this episode, “Beginning of the End,” among John Terry’s credits?! That seems like confirmation. Here’s a link to a posted screencap of the man in the chair, which I’ve brightened a bit to make it more tantalizingly clear.
