Seeing how thier innocence was broken by the same person who killed Allens', I wonder if it will be that easy to do. Although I'm quite sure that Hoshino will make their comback later, I'm interested in the way it will be done. Here lies the potential of the same thing athat is going to happen with Linalee - the change of specialization. I can see their innocence switching types from equipment to parasytic. The base for this claim is the method that was used to restore broken innocence once already - in Allens' case. Back then a huge level of synchronization was needed, the one that both Kanda and Lavi are yet to reach. So why not do it in th process of restoring?
