The best candidate is clearly Nahla Ake (Holly Hunter), an ex-Starfleet captain whose half-Lanthanite heritage means she has been around long enough to remember the good old pre-Burn days of 120 years ago. But a fraught opening flashback reveals why the long-lived Ake resigned from her position. Starfleet protocol forced her to separate a young kid called Caleb from his desperate mother (a brief but effective cameo from Tatiana Maslany) because their starving family had fallen in with a bristly gangster called Braka.
