Walking over towards the console Jack goes to shut the doors leading to the console room. Jack knows he'll be responsible for him as soon as The Doctor gets tired of his itchiness. He moves his hands along the brim of the console and he pulls out a glock from under it.

He's had hundreds of years to perfect his skills from the Agency. Those same skills made him stinking wealthy and kept him occupied for the time being. "We can work on the manipulator a bit later but I wouldn't using it."

"I'm over two thousand years old worth of positive. The Daleks weren't shooting to stun that day." Jack slides the hammer of the gun back and he ponders the demonstration on himself. Jack puts the gun to the side of his head and he pulls the trigger. It's not an impressive show as the side of his head finds itself somewhere else in the TARDIS and he collapses in a heap.

It's a quick death and it's an even quicker fix as the energy from the Vortex begins to mend him back together again.
