The theory that I usually go with after my main one would be the one Ilex presented in her story 'Mended.' While I did enjoy the angst, I'm glad they were finally able to be happy together and have no more secrets.But I'm interested in hearing your other potential theories, too.
For me it's that I'm a huge Team Rocket fan. I like to imagine it as being very involved in the going-ons in both Kanto and Johto (like funding the Pokemon League to seek out possible agent candidates for example), so I tend to connect a lot of characters to it in some shape or form. Some of these theories I've mentioned in the Nevermet Shippings thread (Diamondshipping and Tyson being Prof. Oak's son, and I'm liking zel's idea of Bashou being Prof. Lund's son.) So I guess I've never been into Haleshipping because he wasn't in TR and I never figured him into it. (Though that does trigger some plot bunnies in my head. Where does he get his funding from?...)Although another interesting thing that I'm noticing (thanks for stirring the pot, Giovanni) is that everyone pretty much presumes it's all Giovanni in the past, all the time. I wonder what keeps Spencer Hale from being a viable romantic option? Surely Diamondshipping is win for all sorts of badassness, and we've got a semi-canon nibble (as much as Live can be considered a canon, anyway), but Spencer's an option too (after all, she's concerned enough to demand to go along at the beginning of 3--of course that's her friend, but what can she do?).
(I guess what I'm really trying to say is, where my Elder/Haleshippers at? Do they even make y'all any more?)
It could also be that he hasn't been mentioned since the third movie, so he's "out of sight, out of mind" somewhat.
I guess that's the only solace to come out of that. ;_; I really wanted to see their new eyeballs too *sigh*I know, right? We need our extended family fix! :( At least they know they can leave everything in Tracey and Gary's capable hands...
