A Detroit blood bank worker who delivers human victims to Xindi-Reptilians hiding in the past.
Loomis is an employee at a blood bank in Detroit in 2004. In Carpenter Street, Archer and T'Pol, sent back in time by Daniels, see him leaving an abandoned factory where three Xindi-Reptilians are developing a bioweapon and follow him home.
Under pressure, Loomis admits he has delivered six people, each with a different blood type, to his mysterious employers. Archer poses as the next victim to get inside. Loomis interferes during the confrontation and helps the last Reptilian get away for a time, though the plot is stopped.
