He is absent in "Dead Man's Chest" but reappears in the third movie. Between the events of "Dead Man's Chest" and "At World's End", Lieutenant Groves is appointed as Lord Cutler Beckett's second-in-command aboard HMS "Endeavour". He stars in "At World's End" aboard "Endeavour" and is present when Captain Jack Sparrow makes a daring escape from Cutler Beckett's grasp. He admiringly wonders if Jack plans everything out or just makes it up as he goes along, but is scared off by a glare from Beckett. During the final battle, he asks Cutler Beckett for orders as "Endeavour" was being pounded by "Black Pearl"s and "Flying Dutchmann"s cannon. Beckett remains in a state of shock during the entire battle, forcing Lieutenant Groves to order the crew to abandon ship.
