This one is during Ann and Erik's early years. It covers the promise Erik mentioned in 'Face to Face'. That's about all you need to know. Phantom isn't mine.
...: Yet again it doesn't work :...
"I'm only trying to help!"
"Well don't!"
The two teens glared at each other. Ann was furious at Erik for scaring her friends with his ethereal voice through the walls. He was mad that she thought he'd need to be taught proper manners in regards to ladies. They then fell into an argument over her constant 'barging into his home' despite the fact that they were in her dressing room.
"Why can't you leave me alone?"
"Because no one deserves that. Not even you, you horrid little beast! Goodness, why do I bother? You never listen to me anyway!"
He grabbed her arm roughly and dragged her around.
"Don't… call… me… that!" Erik warned.
"Don't threaten me, Erik."
He chuckled humourlessly.
"Or what? You'll give me a dirty look?"
Ann reached out behind herself and pulled down on a sheet of fabric draped along her wall.
"Give yourself one!"
It fell, revealing a large wall mirror.
The young Phantom's eyes bugged and he started to tremble before running from the room, yelling behind him,
"I hate you!"
She went to apologise an hour later and found him sobbing at the edge of his lake.
"I'm so sorry Erik. It's just, you were hurting me and wouldn't let go…"
"Why Ann? Why that? You could have hit me, cut me, called someone… Why that!"
"I'm sorry!" She tried again, trembling with her own tears. "I… I promise I will never do it again. Not ever."
He sniffed, composing himself.
"Did you know you can make mirrors that you can see through?"
"No."
"I've made one… I thought about putting it up in the House somewhere…"
"Not in my dressing room I hope." She joked.
They both smiled sadly.
