Michael looks up Mahone's ex-wife and discovers something telling about his pursuer. And Sara figures out what the numbers on the origami birds mean, learning where to meet Michael in the process. Trouble is, so do Kellerman and Mahone. Linc and LJ head for the rendezvous point, too. Meanwhile, C-Note returns to Chicago for a rendezvous with Kacee and Dede, but Lang gets to them first; and T-Bag seeks out Ms. Hollander, but stops first to buy some flowers.
