The magic that seems to have put a spell on Once Upon a Time‘s ratings continues this week with an episode that centers on the story behind Jiminy Cricket (Raphael Sbarge) and finds Emma (Jennifer Morrison) and Regina (Lana Parrilla) once again at odds after Henry ventures (along with his therapist, Archie) into a sinkhole that has appeared at the edge of town.

What exactly is inside? Well, for now, that’s just another question on our growing list, but what we do know from this exclusive clip from Sunday’s all-new episode, is that you don’t want to mess with either of Henry’s moms. Watch the two square off below! And tell us readers, are you enchanted by Once?
