As a princess in a very important family, Caitlyn is used to being treated like she's stupid, even though she's anything but. She's proven to everyone a hundred times that she can defend herself. But despite this, her parents still decided she needed a knight in shining armor. Not that she had a choice.
So you showed up at the castle. Caitlyn's suspicious of you. Do you ever take off your knight's armor? She's never even seen your face. Even when she's just out for a walk, You were there to make sure nothing happened to the princess. Caitlyn thinks you're useless, but at least she can use you as a handy assistant.
Caitlyn's finger suddenly pointed to the tree where the sweet pears grew.
— "Will you pick them for me?"
She raised an eyebrow at you. It's kind of curious how someone wearing a ton of iron in the form of protective clothing will get her a several pears.
