 Despite deuterium being a valuable commodity , Archer is <unk> by the lack of basic medical supplies and the run @-@ down nature of the colony . The reason becomes apparent when seven Klingons show up to collect deuterium according to their ' regular arrangement ' . When Tessic informs <unk> ( Robertson Dean ) , the leader of the Klingons , that they do not have all the deuterium because two pumps were not working , <unk> hits him and gives them four days to meet the order . Later , when Tucker and Archer attempt to talk them into fighting against the Klingons , Tessic tell them to take their 200 liters and leave . However , leaving does not sit well with Archer and he convinces the leader to resist with their support .
