What does Vance know?
Vance is following the money. He knows the Major's secret organization has doubled its expenditures recently. He even tracked its purchase of a DNA Sequencer. He's also not happy that this same secret government organization tried to kill him. Did Vance subtly hint that he wanted to extract a small degree of payback for what happened to him at Red Hook? If he gets an opportunity to do so, I wouldn't be mad at him.
But other than following the money, what does he know? Does he know what happened to Fiona Clarke's catatonic patients? Perhaps, they're the reason the Major has doubled her organization's expenditures. She has again hooked them up to an array of electronic gadgetry and is continuing with her "unorthodox" research. I can even visualize it. But this is the moment when my lowered expectations tap my excitement on the shoulder and tells me to calm down. Why get excited about something that won't happened?
Has Ben clued Vance in on the death date? What about James Griffin and Zeke Landon? What about Grace's pregnancy and her ability to receive Callings? Has Ben told him? Does Ben trust Vance enough to share everything with him? More importantly, does Vance have information about some of the things Ben's not willing to share with him?
Vance hasn't been seen publicly since Red Hook; but that doesn't mean he's been out of circulation and not engaged in covert operations. Capt Bowers replaced Capt Riojas at Michaela's police precinct. Vance once got Jared reinstated at the precinct after Jared was suspended for taking the blame for Michaela when she screwed up an undercover operation. In short, he tried to manipulate Jared and force him to spy on Michaela. Vance and Capt Riojas were professional acquaintances. What about Capt Bowers? Does she have professional ties to Vance? Or is she more likely to be a candidate who's working in the Major's camp? Stay tuned.
Here's an additional thought.
Secret information is not always secret
Aaron Glover is a journalist who has a podcast called "828-gate." Glover had information from his source about secret congressional funding ... money to be used to search for the mysterious "Holy Grail." He also knew about a helicopter dropping off the Major at the Red Hook facility an hour before the explosion.
Glover is a journalist. Vance is a professional national security intelligence expert. Which means that Vance should be able to access an infinite amount of information more about what's happening than Glover. And he has the capability to have one of his operatives talk to Glover and get an insight into everything about "828-gate."
Information is knowledge ... knowledge is the proper use of information
Vance should possess mountains of information and should know all about the Major. He should know who she works for, the roles of Unified Dynamic Systems and the Singularity Project in the passenger kidnapping conspiracy; and who was stupid enough to shoot at and try to kill him and the team members of his well-armed, professionally trained TAC Unit.
Robert Vance should be the biggest threat to the Major ... period. If the Major isn't aware that Vance's not dead, she has serious problems. What did she want and do with Vance's deputy, Tim Powell? (Powell is another one of those frustrating unanswered questions.) If Vance knows anything; he knows the Major tried to kill him once and there's nothing preventing her from trying to do it again.
