Watch The Walking Dead season 6 episode 7 live online: Andrew Lincoln talks about characters dying on show

The Walking Dead season 6 episode 7 will indicate that things are taking a more peaceful turn in Alexandria, but that's not going to last for long. Titled Heads Up, the upcoming episode's official synopsis teases that, "things in Alexandria are quiet – briefly."

"Briefly" is right as the official synopsis for next week's episode - also the mid-season finale - teases some insane mayhem in Alexandria. "After having a few moments of peace, trouble finds its way to Alexandria yet again. Only this time, the threat might be too big to defeat," reads the episode 8 description.

Wetpaint has posted an "unconfirmed spoilers" report revealing some key details from next week's mid-season finale episode titled Start To Finish.

As per the report, Giant herds of walkers will break through the walls of Alexandria -- it's fight or die. The website's source also teases that Rick will go on a frenzied walker-killing spree. Besides, the report adds that the episode will feature some major deaths!

TWD actor Andrew Lincoln (who plays Rick) recently spoke about dealing with on-screen deaths of characters and explained how "it's kind of heartbreaking" but "in a beautiful way."

"When we lose a character, it's always one of the more painful experiences," Lincoln told Entertainment Weekly. "But generally they're incredible acting pieces to get involved in. It's a double-edged sword." (via ComicBook)

"It's funny, I bumped into Sarah Wayne Callies [who played Lori] and she said, 'How's it going?' I said, 'It's still the most beautiful job, but it's kind of heartbreaking.' As I go along, we keep losing incredible friends and characters. It sort of kills me doing this job — but in a beautiful way. It's a great story. But every day is unique, and that's one of the things that keeps me coming back for more and wanting to keep pushing this guy and pulling the rest of the cast along with me to create this broken fairy tale."

The Walking Dead season 6 episode 7 Heads Up airs in the US this Sunday, 22 November at 9pm ET on AMC. Click here to watch it online via live stream.
