"We were married once... long time ago,"The Doctor said slowly. He looked at the MAster. "No killing him and its not even worth trapping him." He knew the Master would only find ways to escape. "Please... enough Master," He looked at the Master. The other time lord was looking a bit scared now. There was fear in his eyes. He wasn't wanting to stop attacking the Doctor. He was breathing deeply, his heart rate had increased " Why intefere.. You don't see me or the Doctor ruining your fight with your sister." He smirked.
