hehehe! It amuses me to read the various theories you guys have come up with.
Nice deduction work, there.
I have my own idea, of course, though whether or not it makes any sort of sense is debatable. (and since I know someone is bound to ask, let's say it's something AU-ish after TOGOM because I'm a sucker for this sort of angst)
Thank you so much for all the comments - I really appreciate them; every single one.
