He hasn't been extradited from anywhere to anywhere. He's still serving time in prison for jumping bail, and he will have a chance to argue against his extradition to the US early next year. If he does lose his extradition battle and does get sent to the US, he will have a further opportunity to defend himself against the crimes that he is accused of committing there.

If anyone thinks that Assange was ever in danger of being extraordinarily renditioned to the US from Sweden then they need to consider that a decade ago he was high-profile enough for the Ecuadorians to stick their necks out for him.
