Grey's Anatomy Season 10 returns with its special Halloween episode 7 "Thriller" tonight at 9 PM ET on ABC.

Here's an episode synopsis:

It's Halloween and the doctors of Grey Sloan Memorial are hit with a barrage of spooky patients, which affects their own plans and puts one doctor's well-being in jeopardy. Meanwhile, Derek collaborates with Ben on a new surgical technique, and Richard angers Bailey when he asks a second year resident to perform his next surgery.

Spoilers for tonight's episode up ahead!

If you were hoping the spooky holiday would relieve some of the tension between Meredith and Cristina, think again. It seems Meredith is a little more sensitive about her surgeon skills and hasn't fully recovered from the jab Cristina made about her professionalism.

In the trailer preview for tonight's episode, Meredith reverts to her passive-aggressive nature and retaliates by not inviting Cristina to the Halloween event.

Don't miss another drama filled episode from Grey's Anatomy Season 10.
