Karyn wants to explain

Karyn said, "I wish you remembered growing up as my twin, the same as I remember you. In fact, I wish that, for the next month, you'd be unable to remember any other past for yourself." "Karyn! What are you doing?" "I just want you to understand how this feels for me. This way, at least you can make an informed decision. Besides, I always try to help my sister," she finished, with a smile.
