Elliot *SPOILERS*

Most particularly, Eliot's death.

If they want you to stay in bed, they raise the rails. When someone has open heart surgery, it feels like they've cracked open you chest, because they have. The last scene where he's apparently hallucinating on Demerol, the rails were not up, and he was moving like he hadn't a care in the world. Unbelievable, both on a human and a medical level.
