If anybody needs a human lie detector in their quest for the truth, Mordred's magic ability will hopefully come in handy here! As someone who considers herself a king, Mordred will be demanding an audience with the queen ASAP - as peers more than enemies, at least! Depending on how genuine the queen is, Mordred will be very inclined to help find the princess.

She also acts very masculine (due to hiding her gender her whole life), so I imagine she'll have a couple of mermaids admiring her from afar... :D

Plot-heavy stuff aside, I'm down for doing anything silly with her as well! Learning how to exist underwater is bound to be a hilarious thread with just about anyone.
