OK, I just have to comment: I can conceivably see how Cam was supposed to have been Jason's. After LiRic 1.0 imploded and Jason/Liz reconnected at the hospital after Emily almost died of cancer, then because Jason/Courtney were having issues at that very same time, it makes sense they could have gone in that direction. As to whether or not it was true that they were and it was shot down because of Frons, I have no idea. I know that "rumor" has been around for years, but I've never heard any actual confirmation as to that fact. 

But regardless, I cannot figure out for the life of me how Aiden was supposed to have been Jason's. Jason/Liz were done long before Aiden was conceived, and Guza admitted that at first, after Becky told him she was pregnant and asked him to write in her pregnancy, he was adamant about not doing it. Then changed his mind because a Spencer/Cassadine WTD s/l was too juicy for him to resist. So, again, how in the world was Aiden supposed to have been Jason's? I'm not getting it at all.
