The Walking Dead season 4 finale, which is set to air this weekend, will be shocking.

In an interview with Entertainment Weekly, show creator Robert Kirkman promised that the final episode will "shock people."

The second part of season 4 focused largely on individual characters, and Kirkman said many questions will be answered in the upcoming episode.

Kirkman told EW: "This last half of season 4 has been a character defining group of stories for everyone, but really, Rick Grimes — really finding what this guy is going to be able to do and how he is going to carry on, and is he going to get these people back together, and where is he going to go from here? And I think there are some big questions that are asked that are going to be answered in this final episode."

He warned that what comes out of Rick Grimes will shock people. "This is Rick Grimes being pushed to his absolute limit. And if you think you've seen that before, you haven't. And the Rick Grimes that comes out of this is really going to shock people."

He also hinted that the season finale will end in a cliffhanger, saying, "it's going to be a rough summer for Walking Dead fans waiting for us to come back in the fall."

According to sneak peek promos, Rick, Carl and Michonne arrive at Terminus. It also shows Rick crying, meaning he could be mourning the death of another survivor.

AMC also teased fans with posters with the quote "Who will arrive" and "Who will survive."

The Walking dead season 4 episode 16 will air March 30 at 9 p.m ET on AMC.
