Lily: Don't move a muscle, bitch.

Scotty taking down the Big Bad in "Stalker".
Miller has Scotty to talk to a guy who has been hanging around a local playground. Scotty talks to the guy and realizes he's a pedophile. After warning him never to come back to the playground, Scott returns to find out that not only has the man returned to the playground, he's now talking to one of the kids he noticed him eyeballing earlier. Without saying a word, Scotty merely gestures to the kid, who instantly knows to get out of there. The next thing we see is Scotty beating the crap out of the guy.
Nadia Kosolov is standing on a street corner singing Tom Petty's "Free Falling" when her father shows up. When she sees him she transitions flawlessly into "Va Pensiero" from Verdi's Nabucco, a song about freedom and homesickness, then switches back to "Free Falling". Doubles as a Crowning Music of Awesome.
