so in this universe romulus blew up and picard got some butlers out of it. meanwhile "synthetics" had staged a rebellion destroying the utopia planetia shipyards on mars and wrecking the planet. that would fuck starfleet pretty hard, by all means get section 31 out to wreck shit back. starfleet puts down the rebellion, outlaws cyborgs / AI / whatever, but goes all in holograms, which is probably a better idea anyway.
so it looks like somehow data was "involved" in the making of twins. for one of them, for some reason, romulan space ninjas bust in on her life and try to kill her, picard helps her, she dies, picard is already moving me with his expressions. so he's on a mystery, but maybe with a mobile holodeck. should be pretty sweet.
cut to the other twin on a defunct borg cube doing rebuilding like science when a sinister romulan dude comes and makes friends. on next week's preview, a super burn / prop on picard. he even worked Q with it.
