You were standing between yourself and Clara Oswald, you knew that she had fallen into darkness, you convinced her to come back.

Clara was looking at you, "You think you're trying to take control. I know what you're doing." She then shouted, "No amount of anything would have me come back, I am what both you and The Doctor made me!"

You could not believe what Clara was saying to you, then you saw the dagger she was holding.

Clara held the dagger in her arm, "Now you really have a choice to live or die, you choose!" she laughed in the dark sinister tone.

You tried to reason with Clara but she would not hear you anymore, She Snapped, "SHUT UP, All you do is try to reason, Stop It!"
