A Trill commissioner who in 3189 regards a human carrying the Tal symbiont as an abomination and tries to take it from Adira by force before they can reach the Caves of Mak'ala.
Commissioner Vos appears in Forget Me Not, played by Andreas Apergis. He is the harshest voice at the reception given to Adira and Burnham, arguing that the symbiont should be removed even though separation would probably kill the host.
When Leader Pav merely orders the visitors off the planet, Vos goes further. He and his guards ambush Adira and Burnham on the way back to their shuttle, and Burnham has to stun them.
He is present again at the caves when Adira emerges with the memories of every Tal host restored, and has no answer to it. His hostility reflects the fear of a people whose numbers were devastated by the Burn.
