Notes and TriviaEdit
- During early season six, Ellen Pompeo was pregnant and showing, so most shots of her are above the chest or her belly is covered with something.
- This is the last season to feature Katherine Heigl as Izzie Stevens, also marking several episodes without Izzie. She remained credited for those episodes until she was released from her contract and thereby got removed from the credits.
- Izzie being fired in Invasion and her absence in the consequent three episodes was to give Katherine room on her schedule to film the comedy movie Life As We Know It. She briefly returned for one episode, only to be absent again for two episodes.
- She returned for I Like You So Much Better When You're Naked, which was supposed to be her final episode before her maternity leave. However, while she was scheduled to return for the last five episodes of the season, Katherine didn't return to the set as she was released from her contract per her request.
- This season has the highest number of episodes that are not narrated solely by Meredith, with 6. This record is shared with season ten. In this season, it may also be a result of Ellen Pompeo's pregnancy.
- The voice over of Goodbye is narrated by all main characters at the time.
- The Give Peace a Chance, State of Love and Trust, and Death and All His Friends voice overs are all three narrated by Derek Shepherd.
- Richard Webber narrates the voice over of The Time Warp.
- Owen Hunt narrates the Suicide is Painless voice over.
