You'd think Q would have mentioned this to our Johnny Luke at some point...We pretty much know now that the truth about Jack is something to do with Picard's brain disease, as it was state in episode 8 that Vadic had removed parts of Jean-Luc's brain infected with the disease. So it's going to be an ancient evil that's been passed down the Picard family line, disguising itself as a brain disease. Why only Jack has super powers and not the rest of the family? Maybe the ballsack nanoprobes activated it I don't know.
someone on somethingawful with a history of leaking stuff from production has revealed the the identity of floating head will make you scream "fuck OFF" at the television so that's something to look forward to
I can't let this redjac thing go, and others with better eyes have spotted when Picard told the story to Jack about being trapped in a shuttle with the original Jack Crusher it was in the same system that wolf in the fold was set in and redjac was dispersed in, also if you want to go back and look at the scene where data hands lore the pack of cards, the only card we say the face of is a red Jack.
