Raven is good with sticking to training and supply runs, but can also be helpful... just about anywhere else (not farming or fishing or cleaning, though. Not a chance) and would definitely be trying to keep her schedule as packed as possible.
Molly would be happy with also learning medical stuff and... just about anything. She'd love to get out there and do things.
Paige, if she sticks around, will be happy to keep doing engineering/sciencey type things and the trade team.
