For a brief moment in 2401, Admiral Jean-Luc Picard is Chancellor of Starfleet Academy (“The Star Gazer”, PIC 2x1; Picard is offered the post of Commandant of the Academy in 2364 [“Coming of Age”, TNG 1x19], but turns it down).
Then the whole Borg/Q/Supervisor/Traveler time travel to 2024 happens…
But when that is all sorted out, we do not see Jean-Luc Picard return to this posting. What happened?
Did the time travel create a new timeline wherein Picard was never Chancellor? Did he not go back for personal and/or professional reasons? Did he resume this posting, but we have not seen it (yet)? I feel Jean-Luc would be an excellent Chancellor for the Academy.
