"Doctor, slow down! You're going too fast!" exclaimed a tired Amy. "It's an investigation, you can never go too slow!" replied the Doctor. After walking for a bit, they reached a large sized cave that was filled with diamonds and crystals, the walked into the cave. "This place is beautiful" said Amy in excitement. "And it's the right place. The signal is strong, it's coming from inside there" said the Doctor as he pointed to a smaller cave. As they walked in, they found the body of a young man lying motionless on the floor. "Doctor look, it's a man, I think it's Oswald, that man's friend" said Amy. The Doctor pulled out his sonic screwdriver and scanned the man. "He's not there" said the Doctor in surprise. "What do you mean, not there? He's right there!" replied Amy. "He's there, but he's not. It's like his spirit has been ripped from his body" said the Doctor. As the Doctor backed off the man, he noticed a small crystal-like object placed in the middle of a control panel. "Oh no. We're in trouble" said the Doctor, with fear in his voice. "Why? What is that thing?" asked Amy. "It's a Dream Ray, and it shouldn't be here" said the Doctor. "They take the very thoughts of a person and they make it into a solid image, the perfect constructor. But the dream rays started to get out of hand, taking people's worst fears and using them against them, to harm them. I thought I'd destroyed them all, but there's one left" said the Doctor as he picked the dream ray up. "So, what do we do? How do we get Oswald back?" asked Amy. "We can't, if he was zapped by this thing, he's probably dead, and the other man too" replied the Doctor. As the Doctor tried to take the dream ray away, it began to light up. "We have to go now! It's spiking! Amy, get down!" screamed the Doctor as the dream ray opened and shot a beam of light straight at Amy. "Amy! Amy! Are you alright? AMY!" shouted the Doctor. Amy didn't reply.
The Doctor pulled out his sonic screwdriver and started scanning Amy. "Come on Amy, wake up! You have to be okay! Please Amy!" begged the Doctor as he continued to scan Amy. As the Doctor stopped scanning Amy, Oswald opened his eyes and stood up. "You're Oswald right?" asked the Doctor. "There is no Oswald, only the Intelligence" replied Oswald, who's eyes had turned red with fury. "What are you talking about? We have to help Amy, she's been zapped by the dream ray" said the Doctor. "You can't save your friend, you can't save Oswald, you can't save the man, there all dead" said Oswald. "So, who are you... What are you?" asked the Doctor. As the Doctor turned to Amy, she woke up and stood up. "We are the Intelligence, an intelligent form of life that was inside that device. You call it a dream ray, but it's not, it's a capsule, a device to hold the intelligence inside. One zap from the device and we are automatically transferred inside that person" said the intelligence from within Amy. "How do I get them back?" asked the Doctor. "You don't, they've all been consumed. There is no escape Doctor, you cannot win. One battle that the Doctor will not win. This time Doctor, you lose" stated the intelligence. As Amy and Oswald closed in onto the Doctor, he wondered how on earth he was going to get out of this one. Then, the Doctor pulled out the sonic screwdriver and spiked it. "That's the recall signal for the TARDIS. She's coming back!" bellowed the Doctor. As the Doctor began to smile, the TARDIS materialised around him, Amy, Oswald and the device. "What is this thing?" said Amy and Oswald together. "This is the TARDIS, Time and Relative Dimension in Space, it's my ship, and it's going to help him defeat you" replied the Doctor in confidence. "You cannot win, we will defeat you" said Amy and Oswald. The Doctor picked up the device and plugged it into the TARDIS console. "You say this device was used to hold you right? Well, I'm going to use the TARDIS as a huge transmitter, and it's going to suck you back in, and bring Amy and Oswald back, okay?" said the Doctor. "Try as you might, we will win" said Amy and Oswald. As the Doctor activated the console, the device activated and opened. "Here we go" said the Doctor. The device shot the same bright light from earlier at Amy and Oswald. "NOOOOOOOOOO!" screamed Amy and Oswald as the Intelligence was sucked out of them and back into the device. "Nice, back in the device" said the Doctor. As the device closed, two bright lights went from the device into Amy and Oswald's bodies. "Warning! Exterior area closing, Warning!" said a voice on the TARDIS computer. "Right, we need to get out of here. But first, to save the man" said the Doctor. The Doctor flicked various switches on the TARDIS console, and as he did so, the TARDIS materialised around the man, who was still unconscious. "Warning! Exterior area closing, Warning!" bellowed the computer again. "Alright, off we go" said the Doctor as he pulled down a lever on the TARDIS console, and it disappeared as the planet blew up.
