Eugene had it all figured out now. Somehow, Gothel had come back to life and found another girl with magical hair, and kidnapped her like she had Rapunzel, and raised her, pretending she was Sunflower's mother. That would explain why Sunflower was so much like Rapunzel.
The golden glow of Sunflower's hair lit up the tunnel, and Eugene could see her face. She looked sad, and he realized that she knew that he knew. From the glow, he could see the exit of the tunnel. He knew that he had to get her far away from Gothel, and that he needed to return her to her real parents.
The glow faded, and he grabbed Sunflower's hand and ran towards the exit he'd seen, pulling her along. They came out into the sunlight, and Eugene blinked in the sudden brightness. While his eyes got used to the light, he thought about where he could go that Gothel wouldn't find them. He realized that to keep Sunflower from being kidnapped again, he would have to kill Gothel again.
But before he could think how to go about and do it, he felt something metal hit his head hard. Before he lost consciousness, he realized that he'd been hit by a frying pan.
