'The Walking Dead': Who is mysterious Father Gabriel, and what is he hiding?

Sunday night's episode of The Walking Dead kicked off and ended with a bunch of unanswered questions, especially for folks who have never read the comics. Today, we're going to talk about one of the newest additions to the series roster: Father Gabriel.

Bear in mind, what we are about to cover will include spoilers that may or may not feature in the series, so turn away now or forever hold your peace.

OK, so Father Gabriel is a character straight out of The Walking Dead comic, and guess what? He's hiding something for sure. Gabriel is a man who lives alone at a church, but it wasn't always like that. He had followers, but they are all presumed dead now, and it is all his fault.
