Double Rainbow Dash shipping would be pairing her with two characters at once. Could the community even handle that much romance?
Well, realistically, if you could clone me, it would be forty-six years younger than me. That would be weird. And it would be raised differently than me (I'm not letting my parents near him!), so he would look like me, and he might have a similar personality, but there would probably be subtle differences. But - if you could age him to my age, give him my personality - I think my wife would run away screaming.
