Some time later, we're back at the Harvard lab, where Olivia seems to be going over case files when Peter walks in. They're familiar enough with each other now to greet each other with "hey" and Peter says he heard Emily had some kind of a stroke. "Yeah, the overload electrical activity in her brain was just too much," says Olivia, so it turns out that the thing that gave her her ability also killed her. Kinda like John Holmes! Olivia says Walter told her that even if they'd known, they could have done anything to prevent it. "He says, 'A candle that burns twice as bright, burns half as long,'" says Olivia, and I can see how that applied to Emily, Human Ball of Energy. Either way, Olivia doesn't find a whole lot of comfort in that, and Peter starts pawing at the case files like MAKE YOURSELF COMFORTABLE, interloper, and he notes a picture of the Observer and is all, "Hey, an Observer!" and Olivia's surprised and asks if that's what he calls them, and Peter says it is and asks what they call them. "Well, up until now we haven't called them anything," says Olivia, making Peter marvel at how different things are here. Peter's like the new guy in your office who can't stop telling you how they did things differently where he used to work.
Peter explains the Observers as best he can, that they show up at significant events throughout history, but they're not so much time travels as beings that exist in all times simultaneously. What Olivia really wants to know, though, is if one of them said something about the future, could they be wrong? Peter says he doesn't see how they could. "They don't predict the future, Olivia. They've already experienced it." Peter finally clues in that maybe Olivia's not asking for the fun of it, and asks if one of them made contact with her. Olivia says no, but Peter knows even this Olivia well enough to be unconvinced.
