John expertly disarms a knife-wielding junkie and sprains his arm. No, not breaks, sprains. He then saves his drug-addicted neighbor from himself.
Watson: I'm a doctor, I know how to sprain people.
- Throughout that entire scene Watson is as sarcastic and unthreatened by his attacker as humanly possible. Sherlock's definitely rubbed off on him.
- John was usually cool and sarcastic in the face of danger (a slight exception would be The Great Game when he was wearing a semtex vest, had snipers trained on him and he was worried about Sherlock, but even then he was more collected than any of the other hostages). When he and Sherlock barely knew each other and he thought Mycroft was a villain straight out of the movies, John only betrayed his anxiety when Mycroft got up close and personal about his [not] shaking hand.
John: I'm asking you if you've seen Isaac Whitney and now you're showing me a knife. Is it a clue? [Wiggins gestures for him to get the fuck out] You doing a mime?
Wiggins: Go! Or I cut ya!
John: Ooh, not from there. Let me help. [Steps closer] Now, concentrate: Isaac. Whitney.
Wiggins: Ok, you asked for it. [John wrenches Wiggins' arm and drops him in 5 seconds; he squats next to Wiggins and speaks in a low, confident tone. It's more than a tiny bit sexy.]
John: Right. Are you concentrating yet?
Wiggins: You've broke my arm!
John: Nope, I sprained it.
Wiggins: It feels squishy! It supposed to feel squishy? Feel that!
John: Yeah, it's a sprain. I'm a doctor, I know how to sprain people. Now where is Isaac Whitney?
Wiggins: [Cowering] I dunno! Maybe upstairs?
John: There ya go [pats him on the leg], wasn't that easy?
Wiggins: No, it's really sore! Mental, you are!
John: No, just used to a better class of criminal.
