Percy would likely become more mature. He has already been through a lot, but the relationship with Calypso would force him to think about a more permanent future.

She has been isolated, but with Percy, she starts to trust more and interact with the outside world again. Her powers might also develop in new ways as she has a new purpose in life - to be with Percy and build a future together.
