"Allen gets freaked-out and contacts the shirtless-FBI agent, who had apparently, in a plot right out of Homeland, become obsessed with Kelley, and was sending her shirtless photo’s of himself before she ever told him about the harassing emails."
Excellent analysis overall, except for two points:
1. Broadwell's e-mails were clearly directed at Jill Kelley saying IIRC "Who do you think you are, parading around the base. Tone it down." That is not what Paula Broadwell would have written to the Centcom Commander!
2. The report today is that Jill Kelley knew the “shirtless FBI agent” previously from “an encounter” (some kind of investigation) and that the shirtless episode occurred in the past after that previous encounter, but before the recent events and Jill's involvement with Gen. Allen, IIRC.
So the FBI was drawn in by Jill Kelley, not Gen. Allen. So the excruciating irony is that Jill brought the house down on herself.
No, out there somewhere is the claim that an email went to Allen from Broadwell about Jill...with the theory that Allen is the conduit to the FBI.
