DEREK: "Hey! Good Morning Addison!"
ADDISON: "What's that supposed to mean?"
DEREK: "It's a greeting. Used in civilized cultures by their civilized inhabitants."
ADDISON: "You're smiling."
DEREK: "Yeah, it's called happiness. I understand why you wouldn't recognize it."
ADDISON: "Woah, woah, woah, wait, wait wait. We're, uh, being mature about this."
DEREK: "Yes, we are going to peacefully coexist in this hospital. Unless you've reconsidered moving back to New York. [pauses] Okay then, we will peacefully coexist."
ADDISON: "Interesting."
