Speaking of Simcoes who should be kept alive, we learn that Dylan, not Lloyd is the one who writes the intricate physics formula on Olivia's bedroom mirror. "I always assumed I'd written it. I guess Dylan must have memorized it this afternoon, " Lloyd muses. Olivia sends the children out of the scene yet again -- possibly because they're being paid by the minute and their rates are eating into the show's special-effects budget? -- and asks Lloyd what the meaning of her new bedroom graffiti is. Lloyd explains: "This equation somehow links the QED, the blueprints and the flashforward all together." Olivia asks, "But it's a math problem -- how could it possibly tie all these things together?" Lloyd is lost in reverie as he replies, "It's the tachyon constant. It's the greatest mystery in all of quantum physics. And I have to solve it right now." The two of them sit on the bed, looking as if they'd rather be anywhere else.
And now, Hellinger's team has slaughtered the rest of the SWAT team, put on their goofy Halloween masks, and headed into the building toward Mark's vision of the future.
Meanwhile, Janis is being wheeled in to see the neonatologist on duty at the local hospital. The doctor's totally chill -- "Everything's going to be okay. That's what we saw, right?" Janis, however, is not at all chill: "I haven't felt her move in three hours!" Note to all TV writers who are plotting character's fictitious pregnancies: Go to babycenter.com and read the dang timeline of fetal milestones. Janis is only 14-15 weeks along, and she's a first-time mother; the odds of her being able to do kick counts this early in the game are really, really low. Human biology does not plot along the lines of conception à tiny Tito Puente impersonations in the womb within seconds.
Cut to Wedeck absorbing the news that his idiot underling is in the building with the bomb. "Where I left my car keys," Vreede dolefully adds. Wedeck calculates that there's 23 minutes until the building blows, so they'll fetch both Mark and the car keys.
Olivia may not be a math genius, but she's sure that at 10 p.m., this will all make sense. She then natters on something about living in the moment, but every time I try to transcribe it, my consciousness steadfastly refuses to live in the moment, so we'll all have to settle for knowing that apparently, all it takes to get Olivia into the sack is your kid vandalizing her room with some cosmetics.
