Morgan arrives at the Tower. He needs some assistance with Mo.

Strand declines helping him and things take a gnarly turn.

He does allow Morgan in and makes a deal with him.

The Stalkers arrive and start attacking the tower with exploding zombies.

Strand is scared and Morgan springs into action.

The man says they have until night to vacate the tower.

Morgan tries to help but the people say they see his scope glinting in the sun.

Morgan tries to escape with Mo, but it is revealed that he poisoned Strand.

Strand allows him to leave when Grace says she will move to the tower and help him get rid of the radiation.

When Morgan leaves, he bumps into Dwight and Sherri dressed as Stalkers and they take him to their leader.

Their leader is ... Alicia.

Alicia says she needs Morgan's help to even the odds about what is going on.

When walkers arrive, Alicia's people start shooting at them and they explode, causing a mass wind of radiation to head their way.

They all run for their lives, leaving us to question what could be happening in this scenario.

Will everyone survive or will they die? We don't know.
