You used to date Derek Shepherd, but he decided to leave and now he's in Seattle, with a new life and a new girlfriend

Today after a long and difficult surgery, your patient died, Amelia offered you to go out and have a drink, so you could forget about Derek and your horrible day

At the bar, you took many drinks, and now you're on the bathroom drunk and making out with Amelia, until you pull apart from her, since she's the sister of your ex

Amelia: "Hey, he's with someone else, this is not wrong"
