(A Doctor who and Portal crossover) (This is for both sides of the fandom to enjoy!) (I do not own Doctor who or portal in anyway.) After the Doctor discovers that a man named Cave Johnson meddling in things he shouldn't, the Doctor goes to discuss the dangers of his experiments. Moon rocks, portals, and deadly weapons was just the start. But he arrives to find that things, much worse then he imagined, had taken place. With help of a silent girl, named Chell, with a particular devise and who knows her way around, the Doctor searches for answers and a way out for both of them.
