Fear the Walking Dead season 6 episode 15 won't be coming anytime soon on AMC as the post-apocalyptic horror drama goes on another hiatus. Despite the wait, viewers have been getting information on what's coming next in "USS Pennsylvania."

Fear the Walking Dead season 6 episode 15 picks up where episode 14 left off last weekend. In "Mother," it was revealed that Teddy (John Glover) is planning to destroy everyone using a nuclear missile onboard a submarine in Galveston, Texas.

The good thing is that Alicia (Alycia Debnam-Carey) was able to warn Strand (Colman Domingo) about the danger coming for them. But then, some speculated that the latter will save only himself rather than informing everyone on the impending doom.

Yet, it looks like Start remains loyal to the group as he possibly told Morgan (Lennie James) and others about what Alicia discovered. As the synopsis of Fear the Walking Dead season 6 episode 15 notes, the Survivors race against time to stop Teddy's plan.

In addition, motives will be revealed and convictions will be tested. Morgan and the rest of the group go on a journey as they attempt to infiltrate the beached submarine holding the nuclear missile for Teddy's destruction. They're going to do whatever is necessary to stop a catastrophic event from happening.

Teddy is known for his catchphrase, "The End is the Beginning," and a nuclear missile is one of the extreme versions of it. If he successfully destroys everyone except his community living in a bunker, then this would be the end of many and the beginning for him and his cult on Earth.

Still, Morgan and the group would not allow this to happen and they won't back down without a fight. In the promo of Fear the Walking Dead season 6 episode 15, they seemed to successfully infiltrate the submarine and they're going to fight for their survival.

Morgan and Grace (Karen David) can be seen checking out the radiation levels while talking about their recent tragic loss. The promo didn't reveal whether the group meets Teddy in the submarine, but John Dorie Sr. (Keith Carradine) is present -- hinting at a potential showdown between the two.

It can be noted that John Sr. played a significant part in putting Teddy in jail back in the 1970s, after committing a series of murders. John Dorie's (Garret Dillahunt) father revealed a lot of details about the cult leader and he's going to hunt down the criminal for the second time.

Fear the Walking Dead season 6 episode 15 airs on Sunday, June 6, on AMC.
