It's happened to me too, more than once. It's pretty easy to work around. For instance, I once had a flashback dream sequence involving (Nero?) as a child, that was underlying character development and not 'promo' referred to as a metaphor for something, which completely missed the point and also referred to something which wasn't meant for consumption. And so I simply played it off as the other character was dreaming about Nero and little boys, et voila easy to turn on its head.

Nero's a sneaky bastard, was he spying on Bane long in advance? Did he tap into his voicemail? Did he imagine the whole thing after reading Bane's bio just to be inane (since Bane hasnt promoed yet, and this wasnt on air in the XWF realm, who's to say he didn't just pluck it from the air)? Those are 3 ideas off the top of my head. There are very few situations you can't work with.
