The previous episode of "The Walking Dead" ended with Daryl (Norman Reedus) receiving a mysterious call for help via walkie talkie. Who made this call and why may be revealed in the upcoming seventh episode, titled "Heads Up," as it shifts its focus once more to Rick (Andrew Lincoln) and the rest of the Alexandria residents.
The promotional trailer showcases Rick asking someone "Do you really think you could do that without getting blood on your hands?" While the trailer doesn't reveal who Rick is talking to, a report from the IB Times pinpoints that it may be Morgan (Lennie James).
After all, it was Morgan who kept one of the Wolves alive and later imprisoned him inside one of the houses. That prisoner later turned into a walker. This scene in the trailer may be Rick confronting Morgan about his philosophy against killing and how it might conflict with Rick's more violent method of protecting Alexandria and its people.
There is also a quick shot of someone carrying a gun, presumably to harm one of the other residents. The identity of this person is not revealed but it is heavily speculated to be Ron (Austin Abrams), the eldest son of Rick's new girlfriend Jessie (Alexandra Breckenridge).
During the previous episodes, Ron asked Rick to teach him how to fire a gun and this may lead to Ron suddenly taking things into his own hands.
By the end of the trailer, it is teased that the walkers might be breaching through the walls surrounding Alexandria. This may force Rick and the rest of the residents to arm up and fight in order to attain peace. However, the title "Heads Up" indicates that despite Alexandria attaining peace, it is likely something even more disturbing is coming their way.
"The Walking Dead" season 6 episode 7, "Heads Up," airs this Nov. 22.
