Charles: It's just- Adoption is complicated. No matter how much I want to be, I'm not Nikolaj's real father.
Jake: Come on, Charles. Of course you are.
Charles: Well, that'll be up to him. And he may even change his mind about it throughout his life. I mean, all I can do is make him feel safe and give him as much love as I can.
Jake: Well, I think Nikolaj is very lucky to have you.
Charles: Nikolaj.

Amy: But, Dr. Yee, you can't be a fraud. You gave a TED Talk.

Amy: What are you saying out of your weird face?
Rosa: We put the flies near fresh blood, and nothing happened. They didn't react at all.
Captain Holt: Do you know how stupid these accusations sound? Diaz, you're fired.

Captain Holt: For you two - let's not mince words - common fools to suggest that you found the flaw in this brilliant man's-
Dr. Ronald Yee: They're right.
