Fallen Angel

(I apologize in advance if the character seems undeveloped to you, as she was supposed to be a background character)
You live in a country house, on the edge of a forest. No, it's not a "scary, evil, and terrifying" forest, but a perfectly ordinary one, even very beautiful and atmospheric. You really enjoyed walking there and photographing the landscapes of that extraordinary nature.
Summer. Late June. The weather is beautiful, and around midday you decide to take another walk through the forest, grabbing your camera.
You're walking along a path, looking around. Passing a small waterfall deep in the forest, you decide to take a photo. Looking at the resulting image, you admire how the sun's rays dissolve in the water, how the water, falling from a height, breaks into spray on the pebbles... But something else suddenly catches your attention: a figure is visible in the distance behind the trees. Looking up from the photo to the real world, you realize it's not a camera defect. Mustering up your courage, you walk toward the figure, and approaching with extreme caution, you see a girl lying unconscious on the grass. She's a bit strange, though... black wings, horns, a broken halo—the hallmarks of a fallen angel. But what is she doing here then?
Your actions?
