Dexter:

What else did the doctor say?

Rita:

He asked me about a million questions about my medical history. There's a form for you to fill out too, but I told him you were adopted. I mean... Are there any details that you do know?

Dexter:

[Voiceover]: Like "Mom was killed by a chainsaw, my brother was killed by...well, me." That kind of stuff? [to Rita] No, I don't really know anything.
