Andrew J. West, best known for his role on Greek, will finally join AMC’s The Walking Dead tonight as Gareth, a character promised at the time of his casting announcement to be a major player in the show’s fourth season.Warning: What comes next is a mix of speculation and actual spoilers. If you don’t want to be spoiled, don’t continue down the page.Because of the “major player” thing combined with the “nobody has seen him yet” element, most fans have figured that he will be a fairly major figure at Terminus, where we’ve been headed for the entire second half of the season.It appears they’re right, as an overseas TV spot for the episode features Gareth greeting Rick, Carl and Michonne at Terminus — although not everything goes well (shocking, of course).We don’t know a whole lot about his character, but we’ll go on what we do know here, and try to make some educated guesses.
