"Here's how you put yourself into the movie. You put your hand up," and she raises her hand, covers a bit of the screen before them, "And you picture yourself behind your hand. You're there, see. And you could be a part of the movie. A part of their world--"
Helen looks at her like she's insane (she's high), "This movie doesn't even have a happy ending. Why would you want to do that?"
Dani contemplates, slams her head back against the seat trying for an answer, because the answer she had lived by for so many years has expired. And maybe she no longer needs to live in the film.
"You're a part of something better," Helen shrugs deeper into her seat and sticks her hand in Dani's bucket of popcorn, "Life."
"Did you just put your ing hand in my bucket of popcorn?" 
"No"
"You ing arsehole. I'm gonna make your life ing miserable"
"BUT THERE AREN'T EVEN ANY HOTDOGS HERE MAN"
"Same"
"What"
"Chill" 
Dani smiled the 'frickity frack pedo petes back' smile.
Dani had the figure of a murderer but the sanity of a crack addict which coincidently, she was both. 
*DUN DUN DUNNN*
Dani killed Helen.
The end.
