AMC's hit series The Walking Dead is ending its second season Sunday night. It's been a rough road for the band of survivors, and the series showrunner, Glen Mazzara, is promising audiences that it's not going to get any easier for them.

This season, the show has had three fundamental members of its group join the dearly departed. Sophia (Madison Lintz) and Dale (Jeffrey DeMunn) lost their lives to walkers, and Shane (Jon Bernthall) actually turned into one after an unfortunate and brutal encounter with Rick (Andrew Lincoln). Mazzara told MSNBC, If you count up all the deaths, we're on a big killing spree here. The showrunner confirmed, There's more bloodshed coming. These characters have felt that they are safe on this farm and they've been wrong. I guarantee there will be bloodshed. The show has only 13 surviving members left in its group, and Mazzara stated that nobody's safe.

Viewers might get to see Daryl (Norman Reedus) in a bigger role now that Dale and Shane are gone. If he survives the finale, I would certainly lean on that character heavily, Mazzara told FearNet. He's a viable leader, a viable number 2.  I do think that moving ahead if he survives the finale that that would be a character who would play a prominent role.

T-Dog (IronE Singleton) has been pretty absent from recent episodes, but Mazzara said that we will see some terrific stuff from the character. There's a reason to love T-Dog, he told FearNet.

While Mazzara and cast members have kept a tight lid on the events that will occur in the season-two finale, the showrunner did say that the comic books might hold a clue. The scene in the comic books has different characters and a different scenario, but Mazzara said that it will hopefully be an iconic moment. It's certainly a standout.

For fans who have had questions about the walker virus being spread without being bitten, Mazzara promises answers in the season finale. The season finale of The Walking Dead airs Sunday at 9:00 p.m. ET on AMC.
