There was a knock at the door to Evie's room.
"Complementary room service for the bride." A bass from the other side of the door announced. The voice was owned by an alien in human form. His kind had been trying for months to get roots set in here on Earth, but things kept getting in the way. Not now. He thought to himself. Today they would finally have the necessary DNA collected that would allow his kind to attach themselves to humans. There were 440 types of mitochondrial DNA and these sisters had the last set they needed. It had to be a set, and they couldn't risk attaching to a person before being compatible with the DNA. It had to be complete.

Once they could attach to humans their parasitic nature would take over and they could harvest the humans at their leisure. One last set.

The Doctor picked up the machine, flicked it back to locating the Hyiasam signature. It beeped rapidly....there was a signature in the hotel, outside the hotel, in the church. "Oh no!" She dropped the machine into her pocket and ran out of the TARDIS securing it behind her before running as fast as she could back to the Hotel. "Nora don't open the door for anyone, oh please don't open the door."
