Just days after The Walking Dead Season 4 came to a close, AMC has announced some majoro Season 5 casting news.

Christian Serratos (Rosita), Alanna Masterson (Tara) and Andrew J. West (Gareth) have all been promoted to series regular in anticipation of the show’s return this fall.

This is a logical step, of course, with West portraying the leader at Terminus, where the series will be set on Season 5; and with Rosita and Tara locked in the same train car as the other main characters.

The Walking Dead Season 4 finale set a ratings record for the drama and has viewers already pondering what to expect this fall.

Is Terminus comprised of cannibals, as the graphic novels would have us believe?

Sound off on that theory, watch The Walking Dead online if you need to catch up and grade the finale now:
