Certain websites state that there are 15 episodes of Surface and 12 episodes of Invasion yet people who are selling it (on 'you know where!') say that the complete series comprises of 11 episodes for both of these shows. I've been on NBC for Surface which only lists up to the latest episode (12) so it obviously goes this far if not all the way to 15 but I think that because the others haven't aired yet then they are not on the episode guide. On ABC there is not a list of episodes so does anyone have any up to date info on both please? Thanks a lot in advance.
