I thought that he mentioned that part about "overreaching" b/c the conversation might have been recorded, or the car might have been bugged. Agent Harris really didn't do anything unprofessional in that car during the conversation.tomahawk wrote: He agrees to meet with Tony in a scene reminiscent of other FBI meetings with rats, but its not Tony being the rat, it's Harris. Although Harris tells Tony that he is "overreaching", he eventually comes through with the information Tony wants.
The info that he relayed to Tony about Phil's whereabouts was in private surroundings. The fact that he tried to hide the subsequent conversation from the other co-worker underscores this notion.
