I was happy to been in the company of people once more. Especially people whom I could help. Once the princess (who introduced herself as Lady Deeandra, ruler of Middle Earth) had lowered her sword and I’d explained that I had prior experience fighting the monsters (they were called Zygons) who were tormenting them, she allowed me to help out.
We set out for the caves. I asked everyone to stand back while I dealt with the matter, but the princess insisted on being in front and putting on a brave face. She was so much like Rose, I thought then.
My thoughts were interrupted soon enough,as we were surrounded by a host of Zygons. They cornered us but the soldiers fought back. Many were struck fatally by the poisonous Zygon tentacles, but I managed to pull the princess to safety. We ran out and found our way back to the TARDIS. I was fatally stung by the Zygon, but being immune, I only collapsed when we reached back to the time machine.
