Sunday's episode of AMC's "The Walking Dead" introduced viewers to a new group of survivors, but left us hanging on who they are.

"Always Accountable" saw Norman Reedus' Daryl finding himself a captive of this new group. But he escapes and manages to find his way back to Sasha and Abraham.

The storyline involving the new group is pretty vague, and it looks like viewers will have to wait for the next episode to get their backstory. Also, next Sunday's episode entitled "Heads Up" will solve the walkie talkie cliffhanger from "Always Accountable."

While many believe it was Glenn seeking help, Reedus denied it was Steven Yeun's character and added that the mystery will be solved pretty quick. He also noted that every little thing shown in the previous episode has an impact on how the story moves forward.

"Every little detail is going to come back, pretty much, to the statue that I take from them to the voice on the walkie talkie -- every little thing that we do, even to the point of some of the things that Dwight says resonates and Daryl uses," Reedus told IGN.

"Every single thing that we do comes back, all of it, every single time. Even the walker that I shot trying to get the crossbow out of that bag has a Cherokee Rose sticking on its back; it's a little Easter egg. Every single little thing comes back. I wouldn't be surprised if Scott knew that walker was going to have a Cherokee Rose way back when. He's kind of a mad genius like that," the actor added.

The official synopsis for next Sunday's episode entitled "Heads Up" reads:

Alexandria is finally able to begin pulling itself back together; peace is embraced between the two groups.

"The Walking Dead" is aired Sundays on AMC.
