At this point if they haven't had any curiosity or interest in what's been going on and were basically an asshole for the last 6 years, are going to so shocked and surprised when many won't be willing to explain anything or coddle them - they'll have a LOT of reading & research a head of them.

My response when they finally grasp some important fact will be the living meme of Nicolas Cage "Ya don't say..." and move on.
