Peter pops up to report that the medical examiner says the angle and wound powder burns are consistent with suicide, but the gun only discharged once -- and up until now, Dana's MO has been to try to kill herself with or directly after the suicide victim, and why is that? Lee figures thinks that her soul or energy is bound to her body, so maybe she's trying to go along with the victims. Like a hitchhiker he says, and Peter laughs and says, "A stowaway to heaven?" and Lee and Peter are getting along great, and I think Broyles should co-ordinate with the head office so Peter and Lee can have another playdate really soon. Anyway, if that's the case, says Peter, why didn't she just pick up the gun and try to shoot herself to catch a ride? What changed?
Elsewhere, Dana is in a combination church/library because a nun is bringing her the story that Dana was looking for, the ascension of Azrael, and the nun's surprised she's heard of it, and Dana makes up some explanation about a night class where she's doing an essay on the journey of the soul to the afterlife, and then the nun just tells Dana the whole story about a sinner named Azrael whose soul was condemned to purgatory, and then after years of watching Azrael suffer, the angels asked God to let Azrael free, for some reason, maybe because he was a really good guitar player or would look great in wings or something. God ignored the angels, because fuck angels, really, he's God. And then the angels were all "stupid God" and then they just brought Azrael up to heaven themselves because Azrael had suffered enough and God didn't get all pissed at them because the combined innocence of the angels' souls outweighed Azrael's sins, and so God was like, "That's cool" and welcomed Azrael into heaven, like THANKS FOR RUINING THE STORY, NUN, SOME OF US HAVEN'T READ IT YET. The nun wishes her luck on her assignment and leaves, and Dana unfolds a piece of paper where she's written the train and seat number that bomb-makin' Brian told her.
Back at Brian's apartment, the FBI team is swarming all over the place, and then Broyles seems to notice something a little off about the floor. Pulling aside a rug, the team finds a trap door and some stairs, and they walk down into a workshop filled with lost-cat posters and animal skeletons. "Oh, hello, freak show," says Peter, adding that this guy was clearly nuts, and goody-two-shoes Lee points out that the clinical term is sociopath. An FBI agent digs up an invoice for twenty pounds of plastic explosives that was in the bathroom for some reason. "This guy was making a bomb," says Broyles. "So where is it?" asks Peter.
