I'm seeing a lot of people are actually dismissing The Bride for Hollywood as a concept saying "Oh the Bride was in pieces how would this even work".
Well Igor in last year's maze was one of the reasons Frankenstein faced the Wolfman as he tried to draw them near each other to fight. And he was trying to reboot the lab back up last year while the Bride was there.
Pure speculation but I think the Story will pick up from there. Frankenstein and Wolfman frozen under the castle and Igor reassembling the Bride. And the info from TPU's article suggests her fighting off against the Brides of Dracula which again could be deliberately set up by Igor. And makes sense because Murdy said he wants the Spinoff mazes to be pairs of characters (Frankenstein and Wolfman, Bride of Frankenstein and Brides of Dracula)
Haha I don't think most people even know that these mazes loosely pick up after one another, let alone would be upset at some kind of inconsistency like that.
