See, I think that still works.
You are the guardsman assigned to protect the eight-year-old Prince. You are currently in the middle of the forest because he absolutely had his heart set on "going hunting", and the royal second-grader should definitely not be traipsing around the woods on his own. You let him go a little on ahead and he comes running back talking about how there's a dead girl in the clearing and there's no-one else around and he wants to take her home because she's really pretty, Hans, and she's all alone!
You let him drag you to said clearing and okay, that is one angelic-looking dead child alright, and on the one hand the quality of her clothes and the craftsmanship on the coffin (who builds a see-through coffin?) speak to potential Consequences if you simply carry her off, but also for the amount of vines that have grown on the coffin she looks extraordinarily un-decayed, so you should probably get the court alchemist's opinion on that, and there's no way he's going to come all the way out here in his embroidered velvet curly-shoes. And also this kid is technically assigned by God as your natural superior, or something.
So fine. You hoist the coffin onto your shoulder (it's not like the Prince can do it. He's eight.) and head back toward the castle, Prince chattering blithely all the way. And then you turn your ankle on a rock and suddenly there's a thump and a cough and a lot of shouting from inside the coffin and you have now become a key player in a tense political incident with the next kingdom over.
You should probably ask for a raise.
