The Doctor smiled at Robin after she kissed him on the cheek before blinking dimly as she asked the question. Confusion crossed his features for a moment before the Doctor opened his mouth to say something funny and clever, but before he could utter a word he clutched at his head and screamed as gold fire slashed across his forehead.<br/><br/>"Doctor!" Harme cried in alarm as she watched with horror as the golden blaze engulfed his skull.<br/><br/>"Greme what have you done!" Rogan roared, watching the Doctor writhe and kick from the corner of his eye.<br/><br/><em>"I haven't done anything, but if he's in pain then I wish I had!"</em>Greme jibbed before pointing a finger.<em>"But its just the chance I need. Kill them!"</em><br/><br/>The Antibodies resumed their march towards the Doctor and the others. Their sockets curled into a menacing shape as they edged closer and closer, preparing to rip them apart.<br/><br/>Rogan took this as a sign to start firing and let fourth a brilliant spread of red energy the cut through the first monster and reduced him to dust.<br/><br/>The creatures comrades let out a collective squeal of pain before they lunged at Rogan and began trying to wrestle the gun from his hands. He snarled and snapped at the creatures, managing to get off another shot that blew the head off one of them, but it was obvious that he was no match for their numbers.<br/><br/>"Doctor, whats happening to you?" Harme cried as she knelt by his side while he shrieked in pain. She had provided care for thousands of people in her long life. She knew thousands of medical techniques, cures, diseases, wounds and other injuries, but she had never seen anything like this.<br/><br/>The Doctor had begun to scream something as he flailed and writhed. It sounded as if he was calling out the names of people, but there were only two names that he managed to choke out clearly before the rest got lost in shrieks and gunfire; Amy and Rory.<br/><br/>The Docotr's head touched the floor of the corridor and the world around them jolted and shimmered as the gold fire licked at the ground. The Antibodies, that were in the process of tearing Rogan in two, suddenly let out a wail and collapsed onto the ground, their purple skin turning a nasty shade of dark red which spread along the ground, turning the tiles of the floor, walls and ceiling a bloody red color.<br/><br/>"What's happening to this place?" Rogan panted and winced as he got up from the ground. The Antibodies had pulled his arm out of it's socket, but he didn't let that stop him.<br/><br/>The Doctor had finally stopped burning. He sat on his hands and knees, panting as the excruciating pain left his body, but even though the pain had gone, he still looked as if he was in burning pain.<br/><br/>He took a look at what was unfolding and swallowed hard before croaking; "Allergic reaction. Regenerating energy doesn't agree with the Repicator."<br/><br/>"What does that mean?" Harme asked, worriedly.<br/><br/>"It means that the replicators going to feel very very sick," the Doctor groaned. "And that would be very bad for us, because now he can't concentrate on keeping up the illusion. We'll be absorbed into its body."
