Meanwhile, in Las Vegas ... Dr. Sara's in a ruffly number and looking for Scuderi on the floor of the casino. We pan across to Linc and Sucre both looking very natty in tailored button-downs and black pants, and Linc's establishing that Scuderi's one of the casino's whales (i.e. big-spending high rollers). Sucre heads off to keep looking for Scuderi, leaving Linc and Dr. Sara to trade a little small talk about Michael. Dr. Sara's worried because she still hasn't heard from him, then she calls Linc on the "Vegas isn't my town" nonsense. So Lincoln explains: "Did Michael ever tell you about Mom? They were much alike. They've got the same mind. As Mom got older, she started losing it. We, ah, we later found out it was a symptom of a brain tumor ... as a kid, she got nosebleeds. Then they stopped. In her thirties, they started up again. She, she later died of a brain aneurysm." Dr. Sara says, "And you're telling me this because Michael and his mother are similar in that way too, right?" Linc explains that Michael had nosebleeds as a kid, they had stopped, but recently, Michael's cracked the big 3-1 and the nosebleeds resumed again, so he may have the dreaded brain-tumors-that-cause-aneurysms malady.
We cut to Mahone checking his little positioning device to confirm that Michael's still in place, then heading into the "Cole Pfeiffer" apartment to discover that -- surprise! -- Gretchen had removed the tracking bracelet and left it on the table. All is not lost, however, because Mahone has noticed a small origami swan on the floor, and when he unfolds it, he immediately sees the "GATE" note.
