How can Arya be the next dragon rider if the last dragon egg is in Urubean the capital of the evil empire?

I dont think she is just going to run into the capital, snatch the egg and run away back yto Du wendlewerden or the beor Mountains or Surda or where evr the varden is or where there is sanctuary.


But im just saying that its not a very hight possisbility that she is going to be able to do that unless she becomes real lucky and that the dragon in the egg is going to choose her.

But I hope that Arya will be the next dragon rider.
