The doctor is (back) in.

Jonny Coyne is set to guest-star on ABC’s Once Upon a Time, reprising his role as Once Upon a Time in Wonderland‘s Dr. Lydgate, TVLine has confirmed. The news comes on the heels of David Anders’ announced encore as Dr. Whale/Dr. Frankenstein. Fold in Dr. Jekyll, and you have the trappings for a very unorthodox AMA conference.
