While the character may start off indifferent or ignorant to the lasting consequences that actions in the Material Plane can have, interacting with their fellow party members could help them learn that what may have been a simple jest in the Feywild is now a hurtful act, causing them to gradually develop into a more empathetic person. Having found their way into an alternate realm, a fairy's transition from the Feywild to the Material Plane could make for an intriguing character arc that could unfold throughout the campaign. Perhaps this fairy has always been interested in the workings of the Material Plane and left their village to explore, or maybe they were kidnaped by a malicious wizard and want nothing more than to return home to the Feywild.
It's rather unusual for a fairy to leave the Feywild, allowing the player to craft an interesting backstory for their fairy.
In D&D 5e, Shifters are a sort of hybrid between humanoid and animal. Their defining trait is their ties to a bestial ancestry and ability to take on more animalistic features. However, this also sets the stage for a unique "fish out of water" story. Shifters in 5e are a playable race of people with the ability to take on specific, beast-like traits.
In most cases, faeries are mirthful, fickle, and simple-minded creatures whose attention is as easy to earn as it is hard to keep, which can make creating an engaging player character out of one tricky.
