What to Expect from Grey’s Anatomy Season 21 Episode 16: Amelia Prepares for a High-Risk Surgery
Amelia prepares for a high-risk brain surgery on Grey’s Anatomy Season 21 Episode 16, “Papa Was a Rollin’ Stone.” The patient is a nine-year-old girl, and Amelia seems to be questioning whether it’s a surgery she should even attempt.
This one risky surgery, however, is the only way to save her.

This storyline has Amelia and Monica Beltran working together again, which should be interesting to see. Piper Perabo guest stars as the patient’s mother, and from the looks of the promo video, we’re in for an emotional episode.
Meanwhile, Jo and Link are focused on wedding plans, and Jules and Winston disagree over how to handle a situation with a patient.
Here’s everything you need to know about this episode, including the air date, cast, promo, and how to watch.
