Scream 3 (2000)

Continuity mistake: When Sidney is first going into the house for the end of the movie it is clear that she is not wearing the vest underneath her clothes and as she is walking around or when she is rolling on the ground fighting with her half brother you see her bellybutton but then she has the vest on and it goes over the belly button.

Roman: I'm gonna check this place out.
Tyson Fox: Woah, woah, just wait one damn minute! There's a psycho killer on the loose and you wanna go traipsing around this gigantic mansion? Have you ever actually seen the Stab movies? Every time this dude enters a room he ends up a god damn shishkabob.

Trivia: The plot of Scream 3, which involves the predatory sexual history of the producer of the film-within-the-film "Stab 3," would unfortunately prove even more prescient years later as the predatory sexual history of studio head Harvey Weinstein was made public. His victims included Rose McGowan, who appeared in the first Scream. The Weinstein Company produced the first four Scream films, and after it was shut down the Scream series was bought by Spyglass Entertainment and Paramount.

Question: How does Roman find Sidney's info for the crisis hotline? We never see him use Dewey's phone and I don't think it's possible he attacked Neil because Sidney would've found out about it.
