After being awakened by Commander Tucker, who was unaffected by the anesthetic used by the Ferengi, Sub-Commander T'Pol was able to convince Muk that Ulis was trying to rob him of his share of the profits. Grish's greed motivated him to trust Tucker, who led him, Ulis, and Muk into a trap, where they were ambushed by T'Pol.
Upon recovering, Grish and the other Ferengi were forced to carry all the items they had loaded onto their own ship back onto the Enterprise. They were then allowed to leave aboard their vessel, with Krem, a Ferengi who had been treated with disrespect by the others, now in command. (ENT: "Acquisition")
