Danny: Roger's gone.
Rebecca: No. Roger's loose.
(After being briefed on a seemingly well-rounded and innocent person)
Danny: I don't get it.
Melody: I don't even have a joke.
Web: We have to consider Havens as innocent prey.
Rebecca: Prey yes, innocent no.
Danny: All he was missing was a t-shirt that said "serial killer" on it.
Melody: She's positive he bears the sig. of the pre-filer.
Melody: You like? That's mine.
Web: He researches potential killers. Those that don't meet his criteria, he rules out. Those that do, he executes.
Rebecca: In the way in which they... may have killed.
Danny: It's poetic justice.
Rebecca: We should add him to the payroll.
Melody: A killer who kills serial killers?
(Danny pulls out handcuffs, and Paul pulls out a large knife from the box)

The little girl's cat was named 'Angel' which is a reference to one of Time Minear's past projects "Angel" the series. Also, the cat jumping out of the trunk was a direct homage to Buffy the Vampire Slayer (episode 103-The Witch), which is also a scene that was repeated in the opening credits for the first 2 seasons of the show.
Maybe "a bit" farfetched, but in the scene outside the theater, on the sign the movie "Once More With Feeling" is playing. Adam Baldwin (who stars as Danny Love) was a regular on the short lived sci-fi series "Firefly" by Joss Whedon. Whedon also created "Buffy The Vampire Slayer", and one of the best episodes of Buffy was 607 "Once More With Feeling."
Music featured in the episode included:
"I'mmortal" by Skinny Puppy
