THE STORY SO FAR: You are a kid on a class field trip to a huge gas refinery. You have wandered away from your tour group and discovered giant monsters in a seemingly forgotten corridor of the plant. Running away, you find yourself outside among the plant machinery.
What the hey, in for a penny, in for a pound. You decide to snoop some more.
You turn a corner and nearly bump into two people, but they sure don’t seem like plant workers. One is a man in “a tweedy jacket and a bowtie” and the other is a “striking redhead in a short skirt”. They seem to both be interested in a buzzing metal object with a green glowing tip the man is holding.
They introduce themselves as “Doctor” and “Amy” and say that they are looking for aliens. Something called a TARDIS picked up some strange energy readings, the Doctor says, and the “gas signature” makes him think Macra are somewhere around. He explains that a Macra is a giant alien crab monster.
For some reason you don’t mention what you saw in part IV. Also you don’t try to get away from these two lunatics.
1) You smell something weird. Check it out?
2) Head back indoors.
