Roman and Kate are pleased that Billie was telling the truth, while Abe learns that Larry had access to codes and information that would have made him look legitimate to Billie. She's exonerated and Abe assures her that she will probably get her badge back.

Lexie reads the doctored paternity test results and is thrilled to see that Abe is the father of her baby. Brandon hassles Lexie, who is pleased to show him the test results, but he can't accept that Lexie's going back to Abe after all the times he turned his back on her. Mea
