I think it's trolling. How often have we brought up the subject on this thread alone, lol? BUT you are quite right that there was some foreshadowing regarding the wedding...I just don't see editorial letting this happen though. They've only been married for 12 issues. I think they'd want to have some time to elapse before adding a baby to the mix. That being said: I think it would be very interesting if it did happen. It would sell some issues, that's for sure. I do hope it happens some day.
So, when do we get to know the parentage of those twins? It seems like we've been talking about them forever.
