According to the creator of the cartoon, princess Val is dead for real and it's impossible to bring her back. But that's just... too unfair and grim for the kids' cartoon, so I believe there must be some way to bring her back and let her have a serious talk with Mourgarth again (they used to be friends in the past, till he betrayed her).
Yes, Val is a Healer (race from the cartoon), and Healers can turn into insects. Val could take a form of golden butterfly.
