It looks like the walkers and the Wolves, as deadly as they seem, aren't going to be the only problem in the sixth season of "The Walking Dead." A new trailer straight from the Comic-Con is now on the Web, giving fans a first look at the bloody action Rick and the gang are in for. 

The walkers are in all places. Add to that the ever sadistic Wolves and the conflicting beliefs of the survivors, and all hell breaks loose. The season 6 trailer shows what that looks like. 

One thing the trailer reaffirms is, Rick is becoming uncontrollably dangerous. The video has a lot going on but the heart of it has to be the clash between Rick and Morgan, who arrived at the walled community to the scene of his best pal pulling the trigger on Pete. 

"Morgan and Rick have a particular kind of man love — the fact that he's gone to find Rick, who is the last person left on the planet who knows Morgan. Everyone else who knows Morgan is gone, which is why he goes to find him," Lennie James, who plays the character, said during the Comic Con as quoted by Jezebel. "Morgan is aware of the effect Rick has had on him. [And seeing him kill someone], there's going to be fallout."

Indeed, the juicy trailer upholds that, with the clip centered on the growing hostility of the folks at Alexandria against Rick's ways and trusting Morgan to mend it. 

"I know Rick. I can stop him. We have to," Morgan declares.

At some point in the trailer, Rick exclaims, "Do you have any idea who you're talking to?!"

Rick's disposition is courting many people's distrust and it looks like Daryl will be one of those people.

Speaking of the crossbow-toting fan-favorite, by the end of the action-packed 4-minute trailer, he is at gunpoint by presumably one member of the Wolves. But just as viewers think he is in grave danger, this part of the clip cuts to another scene where he single-handedly batters his captors.
