Olivia and Broyles walk along the sidewalk near Hastings Street (which actually exists in Boston, to my mild surprise) as Olivia agrees with Newton's assessment. "I made an emotional choice. I chose my friend over my responsibility." She adds that they don't know if Walter gave them what they needed, since he has no memory of the interrogation, plus his excised brain tissue is dead. And no sign of Dr. Paris. Olivia carps that they only have more questions. "Who is Paris? How did Newton know about Walter's memories, and why did they let Walter live?" I was wondering about that last one myself. Newton could have just as easily sent Olivia back into the house and had Peter inject Walter with soy sauce if he'd wanted, and Newton would still be just as free. Broyles philosophically guesses, "The more answers we get, the more questions they'll lead to." Olivia says they have no answers, but Broyles doesn't see it that way. "We've given our enemy a name and a face. That's something. And you saved Dr. Bishop's life. That's something, too." And at least they know why Walter is the way he is, even if all hope of fixing him is gone. Broyles insists that Olivia made the right choice; capturing or killing Newton wouldn't have ended anything, "But there's only one Walter Bishop. And we'll be needing him before this is over." He tells her not to be so hard on herself. "We're going to be needing you, too." With that he walks away. So Olivia's position is that she sucks, but Broyles insists that she's awesome. I don't think either one of them really gets how the employee-boss relationship dynamic is supposed to work.
Walter is about to go in for another MRI scan. Before he lies down on the table, Peter blurts, "I should have visited you, Walter. While you were in St. Claire's." Walter easily tells him it's okay and sits down on the table. "If you had, I probably wouldn't have remembered anyway." Peter leaves the room instead of saying what anyone else would in this situation, which would be, "Oh, in that case, I did."
As Walter is slid into the scanner, a version of the Fringe theme cues up, which is an interesting omen; whenever you hear the main titles in the body of a TV show, especially at the end, it's always a sign of something significant coming up. And in this case, it doesn't disappoint. The screen slowly fades to white, until I'm expecting the words "Dr. Walter Bishop, 1946-2009" to appear.
