ABC has released both the stills and synopsis for the Halloween episode of Grey’s Anatomy season 10, episode 7 “Thriller” which tease what will happen when Ben returns to Seattle for a visit.

Ben is making his return to Seattle, but it doesn’t look like there will be much time for romance with Bailey. The stressed out surgeon has her hands full with Weber who she continues to disagree with on his course of treatment. So Ben will make himself busy working with Derek on a new surgical technique – as shown in the stills for the episode.

Recently, Jason George teased that the visit wouldn’t turn out well. “It’s a long distance relationship and that wears and tears on everybody,” George explained.

Take a look at the stills below from Grey’s Anatomy season 10, episode 7 “Thriller” below to see what Derek and Ben will be working on:
