This is a very interesting case. So, things in the CIA really work like its shown in movies. What did we learn from this?
When a CIA Agent approaches you and wants to make you a spy make them sign something like a contract or just show them the way to the door :D
CIA's reputution is already very low because of the latest events but now it got even lower than before (in my opinion)

I wonder whats going to happen with this case...

a promise is a promise.
CIA has to pay up.

although no one has seen any agreement or actual promisses made by the CIA to the guy.

i think if the guy has lived here for over 15 years, and had a job as a banker, he has enough experience and credentials to get another job. why should the CIA pay his bills?

Oh don't worry CIA will now pay more than what it was supposed to pay. It will be much more difficult for them to recruit new spies.

I wonder whats going to happen with this case...

Mr. Doe will accidently step into an open elevator shaft.

[Oh, Shit! ]
