A friend of Malcolm Reed from his training days, contacted by Hoshi Sato during her search for the armoury officer's favourite food.
Mark Latrelle appears in Silent Enemy. When Reed's parents, sister and other relatives all fail to say what he likes to eat, Hoshi turns to someone who shared his earlier years in uniform.
Latrelle is glad to talk about his friend and has stories to tell, but on the question in hand he is as stumped as the family: Reed, he recalls, would eat more or less anything and was never one to discuss his tastes.
His is the last of the calls to Earth. Hoshi then tries a direct approach over a meal with Reed, which he misreads as a romantic overture, before Phlox notices that the lieutenant takes regular injections to control an allergy to a plant enzyme found in pineapple, and the birthday cake is chosen.
