How does Bullet come back into Winter's life, and why does she decide to give him another chance?

Bullet comes back into Winter's life when she runs into him at the party for GS. That night she refuses to go with him, but he gives her a pager so he can reach her later. As she is waiting to board the bus to go find Midnight, Bullet pages her and wishes her happy birthday. He convinces her to meet him at the mall so he can take her to Key West for her birthday. She has no regrets about not getting on the bus as she gets into his brand new Lexus and heads to the airport.
