Since we know Emperor Georgiou is now a member of Section 31 (based on the latest trailer), it stands to reason we'll meet some other members of the organization. So, will we get to meet Admiral Alexander Marcus this season? He was, after all, Head of Starfleet Command in Star Trek Into Darkness and also headed up Section 31. I'd love to see Peter Weller's character return this season as a different version of his Kelvin counterpart in a universe where the Into Darkness characters' fears of war with Klingons have come to fruition. Would he be as big of a warmonger in the Prime timeline or would he be more laid back and mellow? Hopefully we'll find out!
