'The Walking Dead' Season 6 episode 16: Negan threatens Rick and gang; who dies? [Watch online]

Season 6 of AMC's "The Walking Dead" is coming to an end with the episode "Last Day on Earth," in which Rick and gang will encounter bigger threats than walkers as they set out to find Carol, who went missing in the previous episode of the zombie apocalypse drama.

"To save one of their own, Rick's group must venture outside the walls," the official synopsis of the episode reads. "Their experience there will change their lives forever."

According to spoilers, Negan, considered one of the biggest villains to come out of "The Walking Dead" comics by Robert Kirkman, will make an appearance towards the end of the 90-minute episode. Negan's appearance will spell trouble for a fan-favourite — Glenn. In the comics, Glenn is beaten to death with Negan's barbed wire-wrapped baseball bat named Lucille.

Spoiler forum The Spoiling Dead Fans Wednesday posted on its Facebook page a leaked audio of the final scene featuring Negan, the character essayed by Jeffrey Dean Morgan. It reveals that someone from Rick's gang will die. However, the identity of Negan's victim was not revealed.

The accompanying audio features a monologue by Negan where he reminds Rick and gang that they have killed a lot of his men. Negan also tells them that he wants half of whatever they have back in Alexandria Safe Zone.

"I am going to beat the holy hell out of one of you," Negan says to Rick and gang. "This, this is Lucille and she is awesome." Initially, Negan thinks of killing Maggie to relieve her of her pregnancy pains. But then the villain decides to spare her life and does an "eenie meenie miney mo" to choose his victim.
