I dunno. I think we're going to get a twist on that. A Federation dog on to Picard would make sense as the Captain of the Enterprise-E. And it should be somebody attached to him.
This Starfleet is not the Starfleet Picard knew or that we know.
Romulans have always been the enemy of the Next Gen era and the tense cease fire ended with the super nova because the Federation abandoned them. That is not a Starfleet thing to do.
I could totally see the attack dog to get Picard being somebody from his crew SENT in the Enterprise-E. Turning the Enterprise into the villain craft per se and the Captain being sworn to duty with an apparently war-ready Starfleet would be a great flip and juxtaposition of the Next Gen to Picard. Really driving the knife into Picard with a war ready Enterprise with a former crew member would be perfect in my mind. This new show is all about the drama and that would be super dramatic.
And to me, Worf would be the perfect one. It would symbolize another moral compromise on Starfleet. Captain Worf and Picard going at it would be a wonderful full season storyline. Duty, honor, guilt, shame, friendship ... the themes write themselves. If gives Worf a meaty character development and you can end it in a number of ways. To me, Geordi would be less thematic.
I don't expect them to go in that direction but I would love to see it.
