There's an older fellow seen throughout the trailer; first in a vinyard and later in Starfleet Headquarters. Sometimes he is wearing a Starfleet combadge. In the last scene, he is in the command center of a starship and says "Engage!" Who is this guy? (Wrong answers only)
From the trailer we can infer the following: 1) He collects military badges and maybe wishes he had served in Starfleet or maybe some sort of 'walt' who likes to pretend he was in Starfleet 2) He has some sort of gardening skills so maybe he is a landscape gardener? 3) Given the show is called PICARD - clearly a reference to Picard Surgelés - so maybe he works in frozen products. Given he has a bald head - I can only conclude that he is an adopted brother of Sisko. The title
He’s Shinzon, who survived the destruction of the Scimitar along with Data, rapid-ages to his correct age and Picard got him a job taking care of the vineyard while he goes off gallivanting with young people.
His name is Robert (French pronunciation). But his voice is so slurred he makes it sound like Robau. And now I've given you enough clues to figure out the badass plot twist.
