How is this possible? These are clones of you. How could she do this? Do they all know their clones? Are they even alive? Are you a clone? If your sis is a clone of herself, there's a very non-zero chance that you are in fact a clone.
But then how could she clone you in time, I mean, she died right after cloning herself, and you're a good two years younger than your sis, so you suppose you aren't a clone. But that then begs the question, how are these clones of you? You then remember the fact that you can clone things in the future, such is the case with the computer in your duck compartment. So, this must be how she cloned you so many times, she cloned future versions of yourself.
Though this may be the case, that then leads to the next question, why are they so malformed. Like, look at this guy.
