Description of last four episodes released TheWalkingDeadAMC/facebook

The Walking Dead season 5 finale is close and fans are hoping that the show's next big villain might be revealed towards the end of the season.

The show's lead star Andrew Lincoln, who plays Rick Grimes, dropped some hints about the new antagonist during a recent interview.

"There are astonishingly brilliant and thrilling characters that I am convinced we would be idiots not to meet in our journey," Lincoln told The Hollywood Reporter. "I would be very surprised if we don't see Negan on the horizon in the not-too-distant future."

Who is Negan?

Negan is one of the biggest and most brutal villains in The Walking Dead comics. He's the leader of a group called The Saviors, vigilantes who agree to protect weaker groups of survivors in exchange for supplies. Negan is big, mean and carries a bat nicknamed Lucille. (via Cleveland.com)

Fans have eagerly-awaiting his debut on the show and looks like the menacing villain is all set to appear in the upcoming episode.

Meanwhile, AMC has released official synopses of the final four episodes of The Walking Dead season 5. Here's what fans can expect as the season moves towards an explosive finale. (via The Christian Post)

Episode 13 titled 'Forget' - Rick and the rest of the group are struggling to adjust to the Alexandria Safe-Zone they were led to in the previous episode. Tensions soar as they try to fit into the new community's lifestyle.

Episode 14 'Spend' - Will see the group facing additional challenges in Alexandria, leading them to question whether remaining in their new home is a good idea, or whether it would be preferable to be outside facing the danger of walker attack instead.

Episode 15 'Try' - Will see how community life within Alexandria has started to resemble life outside, and Rick and the rest of the crew have just dawned upon the realisation that Alexandria is not the sheltered Safe-Zone everyone expects it to be.

The danger of walker infiltration looms, and viewers may just get to see whether the group decides to stay inside and help defend Alexandria, or bail out on the community.

Season 5 finale, episode 16 'Conquer' - This 90-minute finale extravaganza will feature Daryl getting into grave danger while on the run, and the rest of the group feel like outsiders as they struggle to adjust to the walled Camp Alexandria.

"The group has a difficult time moulding to a new lifestyle, forcing them to consider whether they can be the people they once were," a summary on AMC reads.

The finale episode will eventually reveal Daryl's whereabouts – which will in turn set the stage for season 5. As per a theory posted at the The Spoiling Dead Fans Facebook page, Daryl may have found himself in the territory of The Wolves - one of the groups of survivors (pointing out to signs seen in episode 9 where Wolves graffiti is shown on walls).

The Walking Dead season 5 finale episode is set to air on 29 March, 2015.
