Derek: "I was a jerk. Sometimes boyfriends can be jerks, but it doesn't mean you stop talking to them... You get that I'm saying I'm sorry, right?"

Meredith: "You yelled at me for no reason, and then you walked away. And now you show up here."

Derek: "Of course I showed up. Why wouldn't I? You don't trust me?"

Meredith: "I do."

Derek: "Okay, well, this is how it works. You fight sometimes, and somebody apologizes. From now on, you can expect that I'm gonna show up. Even if I yell. Even if you yell. I'm always gonna show up."
 
 
The expected's just the beginning.
The unexpected is what changes our lives.
