I have to work with an insane, nine hundred year old alien, my wife, and maybe that other woman who came to the camp to unexplode my already exploding universe. And we are going to find a way to do it because the Judges aren't going to have that sort of power. We might have already done it!
Once you start going into that realm of insanity, already have a ship that travels through space and time, finding a way to find my family is probably going to be pretty doable. Even if it's horribly complicated, it's not like I haven't done horribly complicated already.
And of course I'm an idiot. After all we've done, I actually thought I needed a wish from here to do what I needed to do. Amy's right, I'm a moron.
But I'm an idiot who will find a way to make all of you happy even if it takes thousands of years to do it.
