AN: Just for you to know, since I don't know what the Witch's name is, I named her Leanette (pronounced lee -uh -net)
Leanette stared in shock as her foolish adopted daughter ran towards her beloved prince. "No! Rapunzel - wait!" she called out in warning, but it was already too late. The Giant had squashed her in so little time there wasn't even a scream as her death's companion. Just the sickening crunching or bones and the squirting of blood. For Leanette she just watched her world get crushed - for the Giant it was only a mere ant.
Leanette wanted to cry but couldn't - her tear ducts had dried up long ago. Though her voice did shake as she told the others, "Doesn't matter what you say - children won't listen," the words were mostly directed to the baker and his wife, who she granted a child in return for the ingredients that gave her back her youth and beauty. You're a fool, Leanette, she told herself. If she hadn't been so vain - her daughter would've still been alive. The baker's sister would've still been alive. "That," she said to him, as well as the rest of the group. "That was your sister."
The baker was shocked. "How come you never told me?" he asked with a newfound sense of loss.
"I was vain," came Leanette's simple answer. "I never should've - " she shook her head, she couldn't finish the sentence.
"I'm - I'm sure you meant well," said the baker's wife, barely above a whisper. Leanette smiled sadly,
"I envied your parents, Ben," she said to the baker. "They were so happy - beautiful children they had, it was all I ever wanted. Alas, I am a witch, a witch that, due to a genetic defect, will never be able to have children, and I've just lost the closest thing I've ever had to one. It was never my loss though, it was yours, your father's and your mother's loss. I stole her," she bitterly laughed. "Just like your father stole those beans. Perhaps there was another reason why I couldn't have children. I am sincerely sorry, I really am," Then one of the strangest things imaginable happened. Ben the baker and his wife walked over to Leanette and hugged her.
"I forgive you," Ben told her. Leanette smiled.
"Thank you," she responded. "Now there's something I must do, it's only right," Ben and his wife pulled away with puzzled expressions. Leanette looked up at the Giant. "It's my fault your husband is dead! Take me - don't harm the lad. It was I who supplied him the beans which would lead him to your house!" Ben and his wife looked at each other in shock.
"No!" they cried out in unison.
"It was my garden in which the beans grew! If anyone should be punished - it should be me. I deserve it more than anyone else!"
And so Leanette committed a completely selfless act and sacrificed herself to the Giant. She was leaving no one behind, no one in the world was there for her, what could it hurt? A world without witches - it sounded like a good thing to Leanette.
