The Bones sniper arc will be coming to a close as this amazing 6th season winds down. I spoiled earlier that a young and impetuous special agent will put Booth directly in the crosshairs of Broadsky's~Arnold Vosloo rifle. Now I can report that Veronica Mars star Tina Majorino has been cast as Special Agent Genny Shaw. As she assists Booth in a stakeout, her cover is compromised and Broadsky gets the upper hand, putting both Booth and Shaw~Tina Majorio in danger.
