Two new sneak peeks for Sunday’s Once Upon a Time episode “The Cricket Game” seem to give away some big plot developments! Beware of potentially huge spoilers.

Hook and Cora’s arrival in Storybrooke is set to be a dramatic one – and Regina will find herself taking the fall for the murder of a beloved fairytale character. It seems we now know who that will be.

In the third sneak peek released for the episode, Emma and Henry are shown eating at Granny’s, and she tells him about fairytale land. When they leave to take Henry to school, Archie’s dalmatian runs up, clearly very distraught, and Emma and Ruby go to Archie’s place… to see him lying seemingly dead on the floor! Could it be that Raphael Sbarge is really leaving the show? That would be a real shame.

A fourth sneak peek released shows Mary Margaret and David trying to stop Emma from charging after Regina (who they clearly believed killed Archie), and reveal a plan: to lock her up, using fairy dust. Just your average day in Storybrooke, basically.

Check out the first two sneak peeks for “The Cricket Game” here, and head on over to the Hypable forums to discuss the clips we’ve seen so far!

Once Upon a Time returns this Sunday at 8/7c on ABC.
