Charlie Yost

Really old guy was the nickname of an elderly patient (really named Charlie Yost) in a coma at Seattle Grace. Shortly after Izzie had quit in Season 2, the interns left the normal dining area to dine in his room. He only occasionally snored and grunted.

Character History
After months dining in his room, Izzie was shocked to discover he had woken up but he soon revealed that he only woke up so he could die. He starts tearing cords out of the wall and unhooking the mechanisms that are keeping him alive. He stops breathing, but Izzie is able to revive him... much to his chagrin.

In between trying to end the suffering, he gives Izzie some advice. Charlie says if somebody really wants to do something, then they do it — he’ll die if he wants to, in other words, while George isn’t leaving Callie (he knew about the love triangle while semi-conscious in his coma).

Later, Really Old Guy is checking out of Seattle Grace. He's all dressed up and ready to go in his wheelchair. That's when he dies peacefully. Izzie brings everybody in so they can have a mini-memorial for him. After the surgeons each say some nice words, Izzie talks about how Charlie was a bastard, but a bastard who knew what he wanted, didn’t stop until he got it (Izzie was hinting to George when she said it).
