Grey's Anatomy, Season 5

Swinder:
The test impaired your memory to such a degree that I have to strongly recommend you don't have the surgery.

Derek:
Izzie, the test was the worst case scenario. The result has nothing to do with the surgery.

Swinder:
We don't know that.

Derek:
But what I do know is that not operating is every bit as risky as the surgery itself. If not more. But, it's up to you.

Izzie:
What do you think?

Alex:
I think he's talking to you, not me.

Derek:
I'll leave you two alone to discuss this.

Alex:
Ah, I'll come with you. I have a couple of questions.

Izzie:
Wait, Alex.

Alex:
Think about what you want to do for a second, OK? I'll be right back. [everyone but Meredith leaves the room. Meredith closes the door]

Meredith:
You are not having the surgery!
