The first half of "Fear the Walking Dead" season 2 saw the group split into three. While Travis (Cliff Curtis) and his son Chris (Lorenzo James Henrie) went off on their own, Nick (Frank Dillane) decided to go solo, leaving his mother and the others as he searches for a new group and new purpose in the zombie apocalypse.

According to a report from the IBTimes, the synopsis for season 2 episode 8, which officially starts the second half of season 2 and is titled "Grotesque," more of Nick's dark past is going to be revealed. Fans of the series will recall that before the zombie apocalypse began he was a drug addict that caused troubles for his family.

Since he left entirely on his own it is revealed that he will find a new group in Tijuana to integrate with. It is further explained that this new group shares similar beliefs and at first he has a lot to like about them but it is stated that he will be walking into a "dog-eat-dog" kind of world, indicating he'll need to toughen up or be killed.

According to the report, this group he joins sacrifices people to the walkers and it is also hinted that their leader doesn't necessarily believe that walkers are a bad thing, a belief that Nick expressed during the first half of season 2.

Speaking to TVLine, showrunner Dave Erickson stated that Nick's strange views regarding the undead are a sort of fixation that will replace his addiction to drugs.

"I don't know if it's craziness so much as an addiction - he's found his replacement for heroin," he explained. "I think that there's an actual physiological reaction he gets when he's walking among the dead. So it's less that he's lost his mind and more that he's found his new fix."

"Fear the Walking Dead" season 2 episode 8 airs this Aug. 21.
