I can easily GM Jess out of the game; the fact that she's hanging around an unknown trainer with at least a Drapion - one who's probably from as far away as Unova, at that - is awful convenient for that kind of task. So unless I'm mistaken...
[hider=Brief agenda in Santalune]- Get Jess out of the game
- Stop by the boutique (it'll be cold in Snowbelle, after all)
- Not get the Bottle-Opener Badge
- Possibly swing by a Pokemon Center and buy some potions/antidotes/etc.[/hider]
