The scripted Dialogue for the final scene of Brick

In case you missed some important sections, here's the entire story retold by Brendan to Laura in the field of their highschool (quoted from the actual script that Rian Johnson put out online. link is in sidebar):
"BRENDAN: Alright, from the top. You had your fingers in Brad Bramish for appearances and to keep him buying from the Pin, who you were hooked with. Emily came to you and Brad, you saw her for what she was, an insecure little girl trying to get in. She goes on the backburner. Meanwhile maybe you're getting bored, maybe just greedy, so when the Pin scores big with the bricks you take your shot. You hook one, take half, and cut it back to size, but you cut it bad. Maybe accidentally, maybe to down the Pin's operation, doesn't matter. You put it back, but poor Frisco doses off it and lands in a coma.
(voice strengthening) So now the Pin's fuming, maybe he's jealous of Brad, so he comes to Brad's crowd looking for blood, or at least a scape. You know trouble. There's going to be a war over this. And there's Emily. She trusts you. She wants in. It's duck soup.
....
You frame her for the bad brick, then you cut her loose. You turn on your heel and bite her in the throat. Last week on the payphone, Pico and Alexander, she saw something she was scared of. Tug's car driving by, the Pin driving, but she wouldn't have seen the Pin. No, she was across the street, angel. She saw the passenger side. She saw you. She saw you and ran like she saw some devil.
...
BRENDAN And she took the hit. Dode hid her away, but the Pin was on to her, tracked her down, told her to meet him, that they would make good. Gave her a time, and a place. And sent Tug. Just to get the straight. But maybe you had talked Tug up, or maybe he just blew a fuse, but Em sprung it on him that she had her kid, and he did what anyone could count on Tug doing - he hit her. She took the hit for you. You let her take it."


At the final scene of the movie, Brendan calls out Laura on her deceiving intentions. Throughout the movie, Laura has been a character that Brendan never fully trusted. Countless times she offers to help Brendan, and Brendan continued to reject her. It wasn't untill halfway through the movie that he began to let her help him but from a distance.
