On their way out, as Olivia struggles down the Gillespies' steep front steps with her cane, she remarks to Peter that Gillespie didn't fit the suicide bomber profile. Peter waves the cases he's carrying with the drugs and the needle inside, saying it sounds like the kind of injections Walter was referring to, but Olivia still isn't convinced. "Anything else on your mind?" Peter asks as he opens the car door for her. Which is his way of asking about the headache he just watched her get smacked by. "Did the doctors say that would happen?" Olivia lies, badly, that they did, and that it was normal. "We should get that back to Walter," she says, "See if he can figure out where those vials came from." Peter lets it drop. Maybe it'll come up again on the five-hour drive back to Boston? Olivia doesn't seem eager to tell Peter that she's been spending two minutes a day with a freelance rehab bowling alley attendant.
