George and Miranda treat a patient... who it turns out has a bit of a history with Dr. Bailey. O'Malley finds this out as he treats the man, played by guest star D.B. Woodside.

George O'Malley may be a repeater, but he's got himself in the thick of many crucial cases at Seattle Grace. And he's got those puppy dog eyes.

Who knows. It's hard to define George and Izzie these days. Are they dating or just sort of together? They're both surgeons, though, that much is for sure.

George and Miranda treat a patient and an old friend of hers. These doctors always do everything they can for patients, and when it's people close to them, they seem to find another gear.

George and the other doctors try to deal with an influx of patients and cases. Just another day at Seattle Grace.

It's hard to blame O'Malley for thinking so. George is going through a lot, and he seems to relate to others even more so than usual.

Is this the last shot of George O'Malley we will see on Grey's Anatomy? If so, he had a terrific run, and we will miss him dearly.

What a pimp. Look at this guy! Way to go, George!

Meredith finally learns the identity of John Doe. And it's shocking.

Or at least until two of them hook up and things are weird.

George holds Miranda as she gives birth to son Tucker.

Cristina has Burke's cap!!!
