The Doctor

The Doctor and Zack travel to an unknown moon after recieving a distress call on his psycic paper. There they meet David Ranch, Steve and Ben, who are the only survivors of an expedition to the moon. David explains to the Doctor that they have been here for weeks, and so many of their crew members have been killed, recently the person who sent out the distress call.

The Doctor then realises who he is facing, the Vashta Nerada. He tells them all to start moving and to get to the tardis, but before he finishes his sentence Ben tells him that one of the shadows has attached itself to him. The Doctor tells Ben not to move, but is pointless when his whole body disappears. The rest of them make it into a room where the Doctor examines a computer, stating that this must be a new kind of Vashta Nerada. He tells them that it's a herbical Vashta Nerada, which can eat the whole human body.

Soon on Steve dies, with only th Doctor, Zack and David left, the Doctor tells them to go to the tardis while he stays and negotiates with the enemy. When they leave the Doctor sees a floating jacket in the air, stating that the shadows are using human clothing to communicate. The Doctor gives them a warning to stay on the moon and leave earth alone, but when they refuse the Doctor sets the base to blow and uses the tardis to travel back to earth.

On earth the Doctor drops off David, who both says their goodbyes to each other, hoping to meet again some day. David then walks off and Zack asks the Doctor "I thought you were going to ask him to come with us," the Doctor then replies, "I was,"
