Mass Effect 2
Mass Effect Edit
Rentola seems very pessimistic and is not particularly impressed by Shepard or the SSV Normandy: "we asked for a fleet, but instead they sent... you." Rentola survives the assault on Saren's base and joins the other salarians in the Normandy's engineering section after the battle.
Even if Captain Kirrahe survives with a majority of his men, Rentola is still cautious about calling the mission an unmitigated success, saying he defers to Kirrahe's judgment. Otherwise, in the event of Kirrahe's death, Rentola reports back to Shepard that due to their heavy losses their unit will soon be disbanded.
Mass Effect 2 Edit
In the Shadow Broker Base, Mordin Solus's dossier mentions that Rentola served with him and Maelon in the mission to spread the modified genophage cure on Tuchanka and that Rentola was lightly wounded during the mission.
