Grey's Anatomy, Season 6

Alex:
So are you back or...

Izzie:
Oh, did you want me to come back? Cause you told the Chief you had serious doubts about my abilities to be here.

Alex:
What?

Izzie:
You went behind my back and told the Chief I wasn't ready to be here.

Alex:
He was making cuts, I was protecting you.

Izzie:
You got me fired Alex.

Alex:
Is that what you think?

Izzie:
This job was the one thing I had left, the one thing, and you took that away from me. You interfered and got me fired. I have forgiven you for a lot Alex. I've had to forgive you for a lot, but I cannot forgive you for this.

Alex:
You made an assumption. You decided I did something. You didn't ask. You didn't hang around to talk. I am your husband and you didn't give me the benefit of the doubt. So you know what? I can't forgive you either.
