Discovered by Blake and his team in one of the Strata Furnace rooms, he was seemingly put on Whitley's extermination list, as he was alone with a Black Ops soldier intent on killing him. Blake had to earn his trust in order to ensure his collaboration, as Lavelle was very distrusful at first. Lavelle, alongside Blake, Dixon and Temple, fought his way through both Thing creatures and Whitley's elite Black Ops units. Nevertheless, he was killed by the explosion caused by the time bomb that was set by Whitley causing the entire facility to be destroyed. Blake was the only one that made it to the surface and proceeded to the Transit Hangar.
- Lavelle can succumb to the infection and burst out if attacked too much by The Thing.
