"I am glad I only shot the Doctors shoulder and not his chest, But It was like I couldn't see him. I couldn't think clearly and I feel crazy." Jack was looking at Rose and Caitlyn. "And you two can't regenerate like the Doctor, Ohh I couldn't forgive my self if I did anything worse."
He was holding his stomach sick at the thought of harming them.
The Doctor was looking at Jack. He puts the gun in his Jacket. "You alright Jack?" He was worried. "Just breath deeply and try to calm down. No harm was done." 
He smiled a bit and wonders what is going on here. "Lucky its not messing with me, otherwise not sure how we would know what was real."
Jack tried to calm himself and closed his eyes for a moment.
