What happens to McSteamy on the show?

  • Mark is gravely injured in the season 8 plane crash that also kills Lexie Grey.
  • In the season 9 premiere, he initially appears to recover, even joking with the other doctors.
  • His condition rapidly worsens due to internal injuries and complications from the crash.
  • He is put on life support, and a “life support directive” he signed is honored after a period of time with no meaningful recovery.

In-universe emotional fallout

Why the actor left (real-world angle)

  • Eric Dane, who played McSteamy, has said he believes he was “let go” from the show, in part because of rising cast costs and his struggles with substance use, even though budget cuts were publicly cited.
  • He’s also described that time as a difficult period personally and said he understood why the network moved on.
