Emma may be facing one giant problem this Sunday on Once Upon a Time, but two of her good pals will be in for it a week later.

In newly-released photos from the November 11 installment, "Child of the Moon," we see an angry mob fill the Storybrooke town square and we can report why: Ruby, fearful of turning into a wolf during a full moon, is the prime suspect in a murder.

Elsewhere, David will face an issue of his own when Decker (aka King George) threatens to expose him as a mere shepherd and not someone worthy of acting as local sheriff.

Meanwhile, in fairy tale world, Red will bond with Annabeth Gish's Anita, the mysterious leader of a pack of wolves. Click through an assortment of images from the upcoming installment now:
