Here’s a sneak peek for Season 2 episode 8 of the Walking Dead that aired during the finale of Hell on Wheels. It’s titled Nebraska and the teaser reveals two new characters. I’m not sure who they are, but at first I thought the one on the left was Otis. Maybe Rick Grimes and Hershel are seeing things? The right could be Merle Dixon with a different hairstyle.

The second half of Season 2 will premiere on Sunday, February 12, 2012, at 9/8c.

Synopsis – After the barn incident, there is much conflict among both groups of survivors, Hershel wants Rick and his group to leave immediately and Shane accuses Rick to be just as delusional as Hershel saying that Hershel knew about Sophia the whole time and hid her from the group. Dale tells Andrea to be careful about her relationship with Shane since Dale knows what kind of person Shane is and now wants him gone from the group. He also reveals this to Lori, including the fate of Otis.
