OK, so some of us have chosen Harry as the most likely suspect to have fixed Little Chicago. (I was never a big fan of this hypothesis until recently.) Of course I mean an older Harry who time travelled back to the past to do so. Therefore it was TT Harry who hit and ran his younger self at the beginning of Proven Guilty in order to get his younger self out of the way for a while. Before I continue I want to refer to best evidence that this hypothesis is the correct one. From a conversation between Bob and Harry near the end of Proven Guilty about LC:
Bob - "No it isn't," Bob said. "Just really, really, really, really, really, really difficult. And unlikely. He would have had to know that you had a lab down here. And he would have had to know how to get around your wards."
Harry - "Plus intimate knowledge of the design to tinker with it like that," I said. "To say nothing of the fact that he would have to know it existed at all, and no one does."
Well, Thomas may have known, but his ability to do magic and understanding the nuts and bolts of how it works is limited. So Bob may have been hinting it was a man who fixed Little Chicago and Harry's response strongly suggests he was the only man who fulfilled the requirements needed to do the job.
So if you accept that TT Harry fixed LC, that is all well and good, but what else did he do? I mean you don't think an older Harry went through all the trouble it must have taken to travel back in time, and break one of the Laws of Magic, and then just head back home? Recently, I re-watched an old episode of Deep Space Nine, "Trials and Tribble-ations" where Captain Sisco, Dax and company travel back to the Enterprise of Star Trek TOS. Specifically they go back into the episode "The Trouble with Tribbles." It's was really, really well done, and it got me thinking about the mysteries of Proven Guilty and how TT Harry might fit in. Here's part of a conversation between Harry and Ebenezer just a few paragraphs past the one above with Bob and Harry.
Harry- "I think we got played."
Eb - "By the Summer Lady?"
Harry - I shook my head. "I think Lily got suckered just as much as we did."
Eb - He frowned and rubbed at his head with one palm. "How so?"
Harry - "That's the part I can't figure," I said. "I think someone set Molly up to be a beacon for the fetches. And I'm damned sure that it was no accident that those fetches took Molly to Arctis Tor when it was so lightly defended. Someone wanted me there at Arctis Tor."
Ebenezar pursed his lips. "Who?"
"I think we got used by one of the Queens to one-up one of the others, somehow. But damned if I can figure out how."
OK, we know from a WOJ that Mab came out ahead after the events in PG, but during the novel she may have been stuck in her own realm, negotiating with the Black Council and defending her home, or at least holding down the fort in case a second attack came. Harry and his party couldn't have made it to Arctis Tor if Lily hadn't given them some Summer protection, but the Winter Knight wouldn't have had any trouble with the cold. So it's possible TT Harry may have gone to Arctis Tor and conspired with Mab in the events of PG. The last sentence of the conversation between Eb and Harry probably refers to Maeve's manipulation of Lily, but perhaps more subtly it also points to Mab coming out on top in the game; possibly with the help of TT Harry.
Consider - "Someone wanted me there at Arctis Tor." Who fits that description better than a Harry himself? I mean a future Harry who knows what would have happened happened if Molly didn't get help that she needed. Following this logic it was TT Harry who set up Molly to be kidnapped by the fetches in order to save her.
That is as far as I have gotten. I need to reread Proven Guilty to see if I can spot other places TT Harry might have intervened. Of course, if this idea is correct then it is also possible TT Harry is at or near to many of the major events of PG, but doing his own thing; perhaps countering another time traveler as Sisko did in "Trials and Tribble-ations" or gathering more knowledge of the Black Council (or Outsider plans), or both.
For those of you who either came up with or have been on board with "TT Harry fixed LC" the longest, what else do you think TT Harry might have done and how do you think your ideas help explain the events in Proven Guilty?
