When the Krill shuttle crashes into the Orville's shuttle bay, it is met by a team consisting of Commander Grayson, Dr. Finn, Lt. Malloy, and Lt. Keyali. Keyali is head of security, Grayson is first officer, and Finn is chief medical officer. All 3 are appropriate crew members to send into an unknown and potentially dangerous situation where there may be casualties. Malloy is the ship's helmsman. Not only is there no reason for him to have gone there, but he would be needed on the bridge during a tactical situation like the one the Orville found itself in ta that moment. He was only included in the group so that he would recognize his old friend who'd been piloting the shuttle.
