Peter says he knows profiling is one of her specialties, but she could at least listen to what he has to say before she just dismisses it out of hand. "Well, he's not the guy we're looking for," says Olivia, tersely. Peter wants to know what he's missing, since this Whelan guy ticks off all the boxes: loner type who has difficulty making friends, who more than likely has parents who are either living far away or deceased. "Therapist says he displays symptoms of narcissistic personality disorder, which means caring about other people is not exactly his strong suit."

Olivia just says again that he's not the guy, and Peter presses her on why. "Profiling is not just about checking off the facts. You have to weigh them. You got to feel it in your gut," she says, which still doesn't satisfy him, and she finally snaps, "He doesn't love her. Whoever's out there fighting to give Amanda back her life, even though she chose to end it, loves her. OK?" So Peter knows this isn't just about this, but is also about that. She realizes that she's being a little short with him and says she's sorry. He tells her not to be, even though he clearly wants her to be.

Anyway, then he finds Roland David Barrett, who worked in animal research. But then Peter figures it's not him, because he dropped out of the group last spring, and it doesn't take a genius to determine that he dropped out the day that Amanda committed suicide, but Olivia asks the pertinent question.

And then they're racing towards Barrett's house, while Peter fills in more of the background: only son to Nathaniel Barrett, heir to the Stanfield Chemical fortune, which he inherited 10 years ago. "Does his post-doctoral work on cell decay and regeneration, but then quit abruptly because of an onset of severe depression," he says, adding that a few years ago he picked up his work again at the Duk-Hee Genetic Institute, where his research contributed to the creation of synthetic life on the cellular level. "I wonder if he could actually do it," says Peter. "Reanimation."
