@ONL Shit, eternal friendship? I didn't sign up for this D:
In all seriousness though, while they wouldn't know the exact details of his research there would be some indication of what he was after. Library books borrowed, people spoken to, articles published, etc. All these vague and seemingly unrelated things painted a picture that indicated (at least to the BoI) that Atkins was onto something important.
Argus isn't a government agent per se, but he's been contracted by them - that way if the leads are a total bust or things turn ugly, the BoI can just blame Argus and carry on like nothing ever happened.
I'm not necessarily trying to say this IS what is true, but what they THINK is true. The reality could be completely different, and Argus is in for a fun time trying to find out ;)
EDIT: I'll probably post in the IC thread again either when it's both a logical and convenient time to meet Barry, or a second filler post to set the scene beforehand.
