Might as well ask this question about the story, since this has always bugged me: Why doesn’t anyone seem truly surprised with Gordon’s return in HL2? He’s been gone for an untold number of years (20+?) and one day he just pops up out of nowhere virtually unchanged since the day of the Black Mesa Incident. The characters seem to act like they knew Gordon was coming back, but just didn’t know exactly when he was going to show up.
No one apparently presumed he was dead, except for maybe Breen, who seems to be the only character that is somewhat caught off-guard by Gordon’s return. If Breen knew that Gordon was going to eventually return and fight for the resistance, he likely would have started a smear campaign long before he ever showed up to try to foster distrust among the rebels and general population. (Breen might have known of Gordon’s eventual return, but didn’t think of Gordon as any kind of threat. However, his tone of voice when Gordon teleports into his office suggests otherwise.)
Perhaps the resistance bought Gordon from the G-man, but the G-man, being enigmatic as always, never told them when Gordon was coming back. It would tie in with Breen telling Gordon that his services were up for the highest bidder (I’m guessing that Breen came to know of Gordon’s “employment” by the Gman after Gordon’s return, but how he found out is still a mystery. Breen might have gotten the knowledge out of a rebel/vortigaunt, maybe the Combine became aware of the Gman’s activities and told Breen, or possibly he had met with the Gman himself.), and it would explain why the resistance seemed more surprised at the timing of his return rather than the fact that he returned at all.
Maybe I’m just reading into all of this too much and everyone was taken by complete surprise when Gordon came back, but the writing/acting just didn’t reflect it as much as I thought it would.
I’d love to hear someone else’s take on this. If another topic for specifically plot-based theories/inquiries would be more appropriate than just posting this in this topic, I’ll gladly make one.
(P.S. Italics are fun.)
