The Doctor smirked. He knew that was going to work. He looked to Seclusion "Well we cant leave you here and do need to stop the vampires." He was looking serious. He looked to Jack again and back at her. 
"PLus I am being careful."
Jack got ready to shoot again, He glared at the vampires "One step closer and I shot." He wasn't worried about himself as he knew he would live always.
