After he left I stopped screaming, and began thinking of ways to get out so I can go outside and see what was going on. Then I remembered that I still have the key to they TARDIS. Maybe it fit into the handcuffs as well. I just want to tell you how hard it is to put a key in a lock you can't see with your hands backwards. It. Is. Hard. But eventually I got it in and it did work! A TARDIS key can unlock TARDIS handcuffs. I ran to the door, opened it slowly in case the Doctor was there, and ran like the wind to go investigate why we came here.
