Not only will Sheriff Mills (played by Kim Rhodes) make another appearance, but “we’ll see one character that we introduced last year in ‘The Purge,’ Sheriff Donna Hanscum [played by Brianna Buckmaster], who I think is a lot of fun [and a] wonderful actor,” executive producer Jeremy Carver tells TVLine.

Meanwhile, the CW series’ “musical-ish” 200th episode will feature “just about every character — I’ll say they will be represented — that you’ve ever loved or hated on the show, and I say that very obliquely on purpose,” Carver teases. “So they will be there in spirit.”

The EP also says “we’ll see one other character that we introduced a couple seasons ago who I don’t want to spoil just yet.”

Given that star Jared Padalecki told Zap2It that the milestone hour brings the Winchesters to “a place where they’re doing a play based on the Chuck Shurley books,” could the mystery guest star be Rob Benedict, aka Chuck the Prophet, aka (maybe) God?
