"I see you've been fraternizing with humans," she noted as she looked around and crinkled her nose.
"I'm saving our race," I replied thoughtfully.
"Good for you, but our work here is done. There is nothing we can do for the humans any longer." She stood up and held out her hand for me to take.
"Mother, these are my friends," I sympathetically looked around, "I can't leave them. They need my help."
"Yes, and I am your mother and your superior and you will answer to me!" I could tell her anger was rising along with her voice.
"No!" I cried and stood up to face her, "I will stick with the human's until the end!"
Tonks sniffed and Molly Weasley was crying.
"I see," she said, "Well if you will not come with me now, you may not come with me ever! I ban you! You are not fitting to be a mermaid!"
I fell down onto the floor as she waved her hand and turned my legs into a tail. She waved it again and my tail was gone once more.
"You wish to stay with humans. You will remain one of them. I am sympathetic; you can keep your magic if you promise to never return to any of us again."
"I will gladly stay away." It was amazing how we both kept our cool. She spun on the spot and in an instant was gone. All that was left where she stood was a small puddle of water. I dropped down on my knees; a wave of grief washed over me and broke into heavy, uneven sobs. Someone was trying to calm me down. With much effort, I stood up and spoke.
"I wish to return to Hogwarts," I said.
"It's too risky," said Lupin, "Only one more week until summer and then you can see your friends."
I nodded and stalked out of the room even though I did not know where I was going.
"I've prepared a room for you upstairs," Molly Weasley called up at me at as climbed the creaky staircase, "second door on the left!"
I entered and collapsed on the bed in a fit of sobs. And that was the same position I fell asleep in.
