The Master was stunned, "I uhhh..." Suddenly he had an idea, "Blaming me...? How DARE you! Jack, I have been in a quantum locked state in time trying to coboard my own people out of the raging inferno that is the time war! If i failed in saving any one, its because i was trying to save my self, My family, MY PEOPLE!" He was breathing heavy, His regeneration was still working on him and he was very very weak. "Jack..Im sorry...I'm so so sorry." He went down to one knee and held onto a railing to keep from falling over, "I was scared, I was stuck, I didn't know what to do." He produced a single fake tear.
The master was wavering, his legs were wobbly and he couldn't stand, It did help him sale his lie to Jack however.
