The Halloween-themed Grey's Anatomy Season 10 Episode 7 was a memorable one.
Eerie patients arrived at the hospital on October 31. One of them puts a doctor's welfare at risk. Derek and Ben, meanwhile, teamed up for a new surgical procedure.
Elsewhere, Richard requested that a second-year resident perform his surgery, and Jo and Alex weren't communicating (though she looked amazing as Tinkerbell).
Also, things became even more awkward between Mer and Cristina when the latter found out that she was not even invited to the former's big Halloween bash.
