"The Walking Dead" season finale will be "complete and utter chaos"

(CBS News) You thought last night's episode of "The Walking Dead" was a shocker - just wait until next week's season two finale.

"The finale is probably our biggest episode so far," "The Walking Dead" creator Robert Kirkman told the New York Daily News, adding the episode will be "complete and utter chaos."

"The cast we begin the episode with is radically altered by the end of the episode," Kirkman told the paper.

That was also the case on Sunday (SPOILER ALERT), as tensions between Shane (Jon Bernthal) and his one-time best friend Rick (Andrew Lincoln) came to head, with Rick stabbing his ex-buddy to save his own life. When Shane reanimates as a "walker," Carl (Chandler Riggs) blasts him in the head to protect his father.

TV Guide asked executive producer Glen Mazzara about killing off Shane.

"It is a great loss, but I think that the way Rick kills Shane proves that," he said. "Shane's spirit still lives. Shane was right in most of the decisions he made ... and I think that Rick's humanity is always his flaw. But I think that he understands now that Shane was right. It will be interesting to see the effect on Rick."

Apparently, more surprises are in store for next Sunday's episode.

"I think in the finale, all hell breaks loose," Mazzara told TV Guide. "The time for eulogizing is over, and it's just time for survival."

"The Walking Dead" season finale will air Sunday at 9:00 p.m. ET on AMC.
