A pleading from Henry. A new scheme from Regina. A sentence of death for Charming?!?

All these developments and more are covered in the following Once Upon a Time sneak peeks, which are courtesy of this Sunday's "An Apple as Red as Blood."

Look for the return of a fan favorite during the installment, someone Regina hopes can assist her dastardly, magical plan; while, in fairy tale world, Snow White enlists the help of a few classic characters in order to save her love's life.
