Okay, I'll come out and say it: my favourite part of "To Sleep In Time" was not any of the Robins, or Bruce, or Babs, but Cass. I mean, there was no doubt that any of the others was going to be priceless in Gotham-gone-fairy-tale, but who'd have thunk Cass would work so well? And the Queen of Fables setting her throne in Arkham still occasionally pops up in my nightmares.
