The Doctor always loved to criticise the way Jack walks into a threatening situation with gun drawn. But not everybody is a pacifist Time Lord, and not everybody can afford to snub weapons when they're going into dangerous situations.

So maybe Jack doesn't need to protect his own life, but he doesn't like dying, even if it's not exactly fatal to him. For one, it hurts like hell. For another, the people with him don't have the same capability to bounce back.

He wasn't expecting a shield to pop up in front of him. And even if his Webley won't work on it (which he can't tell), he turns, aiming, hands steady as he glares at the woman behind the shield.

But she's got style, at least, and he lowers the pistol a fraction, his sly smile almost automatic.

"I'm not so sure about that. You never know, it might be fun."
