It seems like more drama will be involved in the upcoming midseason finale of "The Walking Dead" season 5 this coming Sunday.  Executive producer Gale Anne Hurd warned fans to brace their hearts for the upcoming episode titled "Coda." 

"I would say make sure that you have a seatbelt on your couch and a lot of tissues handy," she told E! News. "I would say it is heartbreaking. It is, I think, completely unexpected and a fantastic way to end the midseason." 

Actor Norman Reedus, who portrays the role of Daryl in the hit zombie survival drama series, also warned fans about the upcoming midseason ender where he and the other survivors join forces to rescue Beth (Emily Kinney) and Carol (Melissa McBride) from the ruthless police officers hiding at Grady Memorial Hospital. 

"He's ready to just burn the place down," the actor said. "It's a different world now, and certain people have gone so dark that you have to put down the rabid ones in order to survive." 

Reedus also said that the scenes in the final moments to be featured in the midseason finale are very devastating. He even let his guard down and cried hard even before the scenes were shot so that when the camera started rolling, his character would not have to bawl down once again. 

But before the eighth episode of "The Walking Dead" season 5 airs on Nov. 30, AMC will feature a series marathon to let those who missed an episode or two catch up.  Here is the schedule of "The Walking Dead" season 5 episode marathon:
