- A panicked Thom urgently hurries the Chief out of Cryo Two

Tech Chief Thom Shephard was an Engineering Technician for the UNSC aboard the UNSC cruiser in 2552. He, along with Tech Officer Sam Marcus, unsealed the Master Chief from the Cryo-chamber before the Battle of Installation 04. He ran the Chief through several diagnostics and tests his MJOLNIR Mark V armor. Soon after, Captain Keyes called the Chief to the bridge of the ship. A single Elite entered the control center of Cryo-B, killing Sam. Thom then told the Chief to follow him to the bridge and rushed out the door, where he was killed by a conduit explosion in the wall.
