Holy sh—! I immediately recognized the singer as Betsy Kettleman, but even while watching Fargo and Better Call Saul's first seasons, I didn't catch that she was also Sheriff Verne's wife. Or maybe I did but totally forgot?

Better yet, Jeremy Davies.

I mean, he already is on Supernatural!

Actually, she did not. She threatened to and he freaked and out did what she wanted rather than have his free will be removed. No telling what else she could have had him do if she put her sway on him. He made the smart choice.

It was implied he died not long after his cover was blown with Alfred. He was having increasingly severe nosebleeds, and it was said there was no cure for whatever was wrong with him. Clones in Gotham apparently have short shelf-lives, like in a lot of sci-fi.

Caitlin Snow went evil for the back half of the season for…reasons. That were never explained and probably never will be. It was pretty damn dumb and uncompelling.

Maybe they filmed a scene that was cut for time.

Julie Newmar.

Or five seasons of an anthology series?
