Sherlock Holmes: Well, she is a retired super-agent with a terrifying skill-set. Of course she’s better.
John Watson: Yeah, OK.
Sherlock Holmes: Nothing personal.
John Watson: What, so I’m supposed to just go home now, am I?
Mary Watson: What do you think, Sherlock? Shall we take him with us?
Sherlock Holmes: John or the dog?
John Watson: Ha-ha, that’s funny!
Mary Watson: John.
Sherlock Holmes: Well…
Mary Watson: He’s handy and loyal.
John Watson: That’s hilarious. Is it too early for a divorce?
