think the issue with Wonderland being a random filler episode will be tying it to main Once. The Bear King was filler, but it did have Zelena, Arthur, and Merida who played significant roles in the whole arc. You can't just cut to an episode where Will goes back to Wonderland and finds Ana stasia with no main stars involved or people will be confused.

The main problem with Bear King was being placed right when "the story was geting good".
