SG-13 team member under the command of Colonel Dave Dixon, considered by his teammates to be a regular "smart ass." On a mission to P3X-666, Bosworth was assigned to patrol the area with Simon Wells, who took a shot in the back by a Jaffa patrol.
Bosworth stayed with his teammate until Dr. Janet Fraiser and Daniel Jackson arrived on the scene to render medical aid. Bosworth traveled to a higher observation point to cover Fraiser and Jackson, but he did not see a Jaffa nearby and, consequently, Fraiser was struck in the chest by a staff weapon blast. Bosworth took out the soldier, apologizing to Jackson for letting him get through -- but it was too late for Fraiser.
