Mason then drives Alpha and Bravo to meet a contact of his who later is to be known as Fiona.
With his attention focused primarily on talking to Alpha and Bravo while driving them to the designated location, he did not see the approaching semi truck that ended up colliding with the T.W.O. vehicle and flipped it over, killing him upon impact.
