The dalek twisted it's weapons array in her direction, and Martha didn't blink. All it would take was that and this thing would shoot her and here she didn't have the means to go back in time or have the death toll waiting like a net to catch her.

"I'm giving you a choice, dalek." Martha quickly said once more in that same authoritative voice. "You've only got this one. Don't waste it." Genuine regret slipped into her tone, and Martha hoped that the dalek wouldn't do anything stupid.

But then it turned it's weapon towards Severus, and Martha was not alright with that. Doing that was cause for her to not give the dalek a chance anymore than she already had and quickly Martha fired a bullet point blank and into the dalek's eye stalk. Jumping back to avoid the spinning of it's plunger, she noticed the removed casing of the shell and fired into it there.
