Lucy Huston : [Knocking on door; Carisi opens it and let's Lucy in] Hey, Detective Carisi.
Dominick Carisi, Jr. : Hey, Lucy, uh, Liv's not here.
Lucy Huston : She's not? I'm a little worried. I sent her to the brownstone of another family I sit for. I had a really strange vibe from the mom...
Dominick Carisi, Jr. : What did Liv say about it?
Lucy Huston : [continues] Well, I haven't been able to talk to her. She sent this weird text.
Dominick Carisi, Jr. : [Carisi looks at Lucy's phone and returns to the squadroom] Guys, we have a problem here. Liv just texted this to her babysitter.
Odafin Tutuola : [Carisi hands the phone to Fin, who reads the text] Stuck at precinct all day. Pick up William from daycare. He has a play date with Lewis today.
Rafael Barba : William Lewis? That's not good when did you last hear from her.
Mike Dodds : I texted her a few hours ago about the push-i rapist. She answered back.
Rafael Barba : But you didn't actually speak to her?
Mike Dodds : No.
Rafael Barba : And now she's sending us a text about William Lewis?
Odafin Tutuola : That's gotta be a code for 10-13.
