Only she's not there anymore, so on come the bomb-sniffing dogs, and Broyles ordering an evacuation. But Dana's already far far away in a field on the other side of the tracks -- nice job securing the train, FBI. You're as good at setting up a perimeter as CTU in any given season of 24. She's carrying the duffel bag, and then she sort of collapses and drops the bag on the ground. Jesus, careful with that! "I'm sorry," she croaks, and then she gets up and starts walking away, leaving the bag behind.

Back on the train, no sooner has Lincoln Lee said, "She's gone," then the train is rocked by an explosion nearby, scaring up screams from the passengers off the train. You think that's her?

When they find Dana, she's lying dead not far from the blast centre. She's dead, and Lee does the close-the-eyes on a corpse thing. He walks with Peter and wonders what changed: "After all that time trying, why is she able to die now?" Peter just says that's Fringe division: "Every answer you get just leads you to more questions." Wait, is he talking to Lee or to us? Lee says it's still a lot more exciting than Hartford, so they should feel free to give him a call if they ever need help, and Peter tells him to be careful what he wishes for. Aw. Grown men making friends!

Back at the Bishop compound, Peter quietly walks in, either trying not to disturb Walter or he's been out killing shapeshifters again. Walter's asleep on the couch, and Peter gingerly takes the half-full glass of milk out of Walter's hand -- and then is startled by his girlfriend standing there in a bathrobe, speaking in William Bell's gravelly voice. Bell says Walter thought it would be a good idea for him to stay here tonight. Peter takes this in with his usual scowl. Also, he made tea, and would Peter like some? Peter looks like he needs something a whole lot stronger than tea (like, say, heroin) but says yes.

In the kitchen, Bell rambles on about Dana Gray while Peter is clearly too tired to pretend to be polite and interested in what Bell is saying. Bell says his first thought was that the energy from the bomb somehow reset the electromagnetic charge in Dana's body, and it was the unique charge that allowed her to die permanently.

"OK, that makes sense," says Peter. No matter how many times I hear that on this show it always makes me laugh! Anyway, Bell now thinks that's wrong: "What if, Peter, this isn't about biology or physics? What if what we witnessed was the very reason that Dana Gray couldn't die?" Peter's not following, so Bell spells it out a little more: because she needed to be here to save those people's lives. "You think it was her destiny," says Peter, skeptically, and Bell goes into a whole thing about "the interconnectedness of apparently unrelated events," and doesn't Peter think it's curious that they meet a woman who can't die at the exact moment his consciousness seemingly returns from the grave? Based on the eye-rolling and head-shaking, Peter doesn't think this is curious. Bell says, "As a scientist, I like to believe that nothing just happens, that every event has meaning." Wait, don't scientists in fact think that things just happen? But Bell continues on, saying that everything has some sort of message, you just have to be able to listen closely enough to hear it. And they're quiet, and they hear church bells ring in the distance.
