Theory 2: MalO is the missing professor's last work, and was instructed to learn as much as possible, and she went to us because either the professor liked us, or my previous theory, she found out her lil' sis had a friend (possibly more) and went to us, but all those memories got blocked by the same force that made both MalO and us forget the one day before the birds all offed themselves like in the movie "The Core."
