Candy is Poison Ivy
Let's see:
  • 1. They are both played by the same actress. I know it doesn't mean anything (every actor in the show had multiple roles), but it helps.
  • 2. Once Candy appears, we never see Ivy again. This was probably done for practical reasons, such as not having to remove Candy make-up.
  • 3. Earlier in the show, Ivy seems to get along really well with Sweet Tooth.
Joker isn't really dead
He's Just Hiding
  • I mean they don't call it Joker Immunity for nothing. He probably faked his death to, I don't know, take a vacation did up the corpse of a random schmuck to look like him and get fished up by the pier. It's likely he hired Sweet Tooth to fill the void in the evil power vacuum.
The Joker IS Sweet Tooth
In this play, ST is pretty much an obvious Expy of joker, while the REAL joker is supposedly dead. However, it's possible joker used his Joker Immunity card once more, and created a new identity for the sole purpose of fucking with batman: Sweet Tooth, I mean it's not outside of something joker would do.
