Another chapter has concluded on "The Walking Dead" TV series. The season 5 finale aired on Sunday, March 29, featuring deaths, a reunion and an introduction to a new threat to the survivors.

[SPOILER ALERT!] First seen in season 1, Lennie James' Morgan is back on the show. He apparently has been been trailing Rick all this season and is reunited with Rick after they last saw each other in season 3 when Rick returned to his hometown.

Morgan saves Aaron and Daryl from a trap set by a new group of villains called the Wolves, which seems to be a new threat to the survivors. The Wolves is also an answer to the "W" mark which has been carved into the heads of walkers seen in season 5.

Meanwhile in Alexandria, Deanna finally changes her mind about Pete after the abusive husband of Jessie sliced open the throat of Deanna's husband Reg. "Rick, do it," she gives Rick the authority to kill Pete. Rick shot Pete in the head, right when Daryl and Aaron arrived with Morgan.

While the Wolves seem to be a villain that Rick and his group will face off in season 6, showrunner Scott M. Gimple says humans are not the biggest threat in the upcoming season. "Season 6 for a good while now, humans have been the bigger threat. At the start of our next season, that will change," he wrote in a letter read by Chris Hardwick on Sunday night's "The Talking Dead".

"I said the show reinvents itself every 8 eps, and we're doing it again, friendos. Now that these characters know they have what it takes to survive, what are they going to do with that power? How will they choose to live? Beyond answering those questions, we're currently putting into motion some of our most ambitious stuff yet, and things are going to get very big, loud and scary," he went on teasing.
