*The cavemen all bear the face of Marcus R. Lehto, a senior employee at Bungie.Paul Russel's personal account. The internal name for the cavemen is "The Gorillehto." The caveman originated as an internal email prank of photoshopping Marcus Lehto's face on a female gorilla.
*The teddy bear being held by cavemen in Sierra 117 bears the caricature of Christopher Carney, multiplayer lead. Originally the bear was to appear in Master Chief's cryochamber at the end of Halo 3. In the Legendary ending, he was to reach down and grab the bear as the door closed.
