Blue falls in a mind control! What Can Red do to save her now?
Well, first, Red would try and spend as much time with her as possible, hoping that by doing stuff with her (like going out on dates), he could jog her memory. If that failed, he'd start to get a little panicked, and probably start telling her about all the times they'd shared together in a hurry, which, since she doesn't recall them, would probably freak her out a bit. As a last resort, I don't think Red would kiss her (to be honest, I think that if Blue didn't know him, she wouldn't let him if he tried), but instead journey the regions searching for the source of her mind control and defeat him/her. I believe that, he'd probably have to battle her beforehand (you've gotta beat the minions to get the real bad guy), and, while he desperately wouldn't want to, would be forced to give it his all and actually try to win, otherwise he'd never save her. They'd enter into an intense battle, with Red being an emotional wreck (on the inside; he wouldn't give his enemies the satisfaction of knowing his inner turmoil) and Blue still under mind control, but something's happening on the inside. Blue's desperately fighting back, but she can't regain her own will. Since Red can't really focus on beating her, she's actually winning and he's getting horribly beaten up. I think that seeing her beloved on the brink of death would definitely snap her out of it, and then she'd defeat the mind controller and rush Red to the hospital, just barely saving his life, and they'd live happily ever after (suckish ending, I know, but the only other option would have been he died for her, which, while he probably would die to save her, I didn't want him to).
What would be Blue and Red's wedding gifts?
As in, what would everyone get them as a gift for their wedding, I assume? Well...
Crys and Yellow would pool their money together and, with a little help from Green, give the two tickets for an all-expense paid honeymoon somewhere super romantic, complete with one night eating at the fanciest restauraunt in town.
Green would help pay for the honeymoon and probably just be helpful by temporarily taking Red's job as Kanto Champion so he could defend Red's position until he got back.
Ruby would supply them with a beautiful handmade gown for Blue and a snazzy tux for Red (for when they go to the restauraunt).
Sapphire would give them lots of different Berries that they could use on their pokemon and also mix with other foods to make delecacies. (I had no clue what to put for Sapphire, really, so I put the first thing that came to mind.)
Gold and Emerald would conspire together and get them condems. XD
Silver would write a heartfelt letter (for Blue's eyes only) wishing her well with Red, telling her he'd always try and look after her, promising that he'd kill Gold and Emerald for their gift (XD), ect. He'd include a very expensive necklace for her to wear along with the gown from Ruby for the night they ate out.
