A New Identity

Emily looked at her new twin with glee. What fun, to have a sister instead of a stuffy, selfish brother. Now she just had to make her all new on the inside as well. But she paused. Now how should it be done, make Dylan remember always being a girl, or just unable to think of herself as any other. Or wipe away that old personality entirely, give herself a sister who was friendly, and helpful, fun and always did what Emily wanted...

That last one sounded best, but it would be so delicious to watch Dylan acting just like a girl, knowing inside he was confused or screaming. Which to choose, which to choose?
