Last Sunday, during the Hell on Wheels Season Finale, AMC aired a brand new bonus sneak peek at The Walking Dead's Midseason Premiere, which gave a first look at new survivors about to enter Rick Grimes's orbit. If you didn't catch it then, the video is now available on AMCtv.com. (Be sure to watch it before the all-new episode airs on Sun., Feb. 12 at 9/8c on AMC.)
