He watched hopelessly as Donna sprinted for the gun.
She knelt down and swooped down to pick up the gun.
"I've got it! But I don't know what to do!"
The blue electrical charge surged through Davros's hand and rocketed out, hitting Donna full on in the chest.
Her cry was the only thing he heard against the crackling of the charge.
The gun flew from her hands as the charge flung her backwards into the air.
"DONNA!"
She crashed into the terminal hard and slumped limply down to the ground, sliding against the terminal.
"DONNA! ARE YOU ALRIGHT DONNA?!"
He panicked, his eyes flicking to where she had landed. He could barely see her slumped form against the terminal, her legs slung out.
He prayed that she was alright, that she would recover and wake up soon.
But she didn't move, no movement at all. No snappy comment, just silence.
