"I don't understand. You said she was fine, but she keeps getting sicker," she tells the doctor. Would you feel better if the doctor started talking about faith instead of facts, Ms. Donovan? The doctor says they're going to run some tests, but the cause of seizures is often unknowable. "You mean, this could happen again?" asks Ms. Donovan, but the doctor doesn't know.

Walter interrupts to ask Ms. Donovan what time her "resurrection" took place, and the priest is all "her... resurrection?" like maybe he thinks of himself as Jesus's copyright lawyer or something, and Ms. Donovan tells Walter that it was just after five in the morning, which turns out to be exactly as Walter suspected. He outlines his theory to Olivia -- who looks kind of uncomfortable to be talking about it in front of Ms. Donovan and the priest. Anyway, Walter thinks Rusk's murder and Lisa's rebirth happened simultaneously, and that it was Rusk's energy that "jumpstarted" Lisa's body and brought her back to life.

"That's absurd," says the priest, who, next Sunday, will perform a ritual in which he believes he will transform wafers and wine into the body and blood -- not symbolically, mind you, but literally -- of a man who died two-thousand years ago who he further believes was the human form of the son of an all-powerful being who made the earth in six days.

Walter doesn't say any of that, but acknowledges it does sound kind of out there and asks for a moment to indulge his fantasies, because "they often lead to a truth." He thinks Rusk's energy brought some of his memories with it, and those memories are fighting to get out.

"Are you suggesting that Lisa is possessed?" says an incredulous priest. Walter wasn't, but he is now, and he's getting a little more testy with the priest: "Now that you mention it, I wouldn't be surprised if numerous possessions were in fact misdiagnosed cases of a phenomenon we are just now discovering."

The priest is dismissive so Walter starts ranting about how he would be, since the church doesn't approve of exorcism anymore. The priest calls them superstition but Walter points out there are examples of casting out spirits right through the bible. And up to recent vice-presidential candidates!

Ms. Donovan interrupts to ask Walter if he can help her daughter, and I have to say that she came down from her "faith is the way" position really quickly. Walter says he needs to have Lisa transferred to his lab, and she gives the OK.
