The two stowaway on a ship to the Citadel, though are uncovered and turned over to C-Sec once they arrive. Though they try to tell of the evidence they have found, they are ignored and told to leave the Citadel. Later, they are suddenly attacked by Jacobus, injuring Tali and mortally wounding Keenah. After being chased through the Citadel, Tali eventually traps Jacobus in an incinerator, killing him, though Keenah collapses and dies.
