Sherlock: Hello Graham. Did you get my text about the murder on the docks?
Greg: Yeah, I looked it over. Nice work.
Sherlock: Good. Thanks, Dad.
Greg: …
Sherlock: Why is everyone staring at me?
Sally: You just called Lestrade “Dad.”
Sherlock: What? No, I didn’t. I said, “thanks, Gad.”
Greg: Do you see me as a father figure, Sherlock?
Sherlock: No. If anything, I see you as a “bother” figure, ‘cause you’re always bothering me.
John: Hey, show your father some respect!
