Paula manages to fight the mental changes enough to tell him what's going on.

As she came closer, Jed noticed a few similarities in appearance between this blonde bimbo and his girlfriend. Maybe they were cousins? Then, her brain-dead expression became something more in-the-moment and serious. "Jed, it's me, Paula. Like I said, that coin is magic. It changed my body and I'm fighting the changes to my personality right now but, it's, like, totally hard." Then, that lucidity began to slip away, and she looked Jed up and down like a piece of meat and giggled. "You probably like these changes, dontcha? Like, before I was a Plain Jane, but now I've got boobies and look sexy!"

Any other day, Jed might have just assumed this was same crazy bimbo who'd taken his girlfriend's phone and was trying to trick him. But when she'd been serious, she'd clearly been Paula, despite the different body. Running a hand through his hair, he thought over the situation. Sure, she was actually pretty freaking sexy, but he loved Paula for her personality, her intelligence, and that was seemingly trapped beneath this bimbo overlay. They needed to try and find a way to turn her back, right?
