With Season 4 of The Walking Dead coming to a close, one big question remains: who will arrive at Terminus? That question is posed in a new poster featuring Rick (Andrew Lincoln), Carl (Chandler Riggs) and Michonne (Danai Gurira) before the penultimate episode "Us" airs Sunday, March 23 at 9 PM ET on AMC. As you may recall, the signs for Terminus indicated that "those who arrive survive." Can Rick, Carl and Michonne make it to this sanctuary? We'll have to wait until Sunday night to find out for sure. In addition, the network has released more photos from Sunday night's episode, featuring Rick, Carl, Glenn (Steven Yeun) and Abraham Ford (Michael Cudlitz).
