Dr. Maggie Pierce (Kelly McCreary) had the biggest Grey’s role across the Grey’s-to-Station 19 crossover as Ripley’s cardiologist.
The crossover started when Grey’s Anatomy’s Dr. Levi Schmitt (Jake Borelli) helped a fallen man on the street in front of a flower shop and brought him to Grey Sloan.
Turns out, that fallen man was the Seattle Fire Department’s Fire Chief Ripley.
Turns out, he was exposed to toxins that quickly shut down his body to a point that not even Maggie could save him.
