Back in the past, Foreman and Cameron can't believe that Chase would be okay with his patient flying off to Mexico City to get what Foreman assumes will be a pig's liver in an operation performed with a hacksaw in the back of a van. Well, I'm sure it will be a clean van, at least. Chase tells them to go tell on him to House, but he's sure House will agree with him that if there's a one in a billion chance to save their patient, they should take it. Foreman says that Kayla is being manipulated by her guilty brother and doctor. Chase is pretty sure that Kayla is just as determined not to die as they are. "She's dying either way!" Cameron says. Foreman points out that third-world organ transplants have a success rate of zero, and that this will just get Chase in more trouble than he already is. Smart of Foreman to appeal to Chase's self-preservation instincts.

Chase enters Kayla's room, where Sam is running around packing her stuff in preparation for their flight to Mexico. Chase tells Kayla that they need to talk. "I made a mistake," he says. He's not talking about the bleeding ulcer thing, though, but about not being realistic enough with Kayla about her chances of survival. Sam begs Chase to stop talking, but Chase keeps going. He says that the flight to Mexico alone could kill her, never mind the surgery or the cancer. "My dad died. Lung cancer," Chase says, and we finally find out what happened to Chase the Elder. Chase says that his father never told him he was sick, even when they saw each other a few months before he died. Chase gets all emotional and says he wishes his dad had told him the truth. Kayla has a chance to tell her daughters the truth and be with them when she dies instead of three thousands miles away from them. "You don't want to do that to them," he says. "I'm sorry, Sam," Kayla says. Sam begs her to keep fighting, because if she dies from this, then it will be his fault. Also, it looks like cancer gives you dark circles under your eyes, if Kayla's and Sam's makeup is anything to go by. Kayla tells Sam that he gave her three more months with her daughters and she got to save her "baby brother" when they found the cancer in her and therefore him. They hug and sob. Aww.
