Hypothetical Gentleman

The  was a being from a hypothetical world that was trying to establish itself as a permanent entity in the universe the doctor lived in by stealing time from its victims. He projected images of a quantum resonator into Emily Fairfax's mind, convincing her husband and herself that she was being contacted by an angel. After the pair built the machine, he linked it to the TARDIS to power the it. He came out of it, to find a police officer, whom he sucked the time out of, leaving him frozen in time. The Doctor called in Emily and Charles Fairfax to determine what the machine was about, and left to find the power source. The hypothetical gentleman then sucked out the time from Rory Williams. When the telepathic Emily read the gentleman's mind, it was filled with images of Sontarans, a peg doll, a Zygon, a Kroton, a Headless Monk, a Silent, a Weeping Angel, and a Krynoid. He subsequently sucked the time out of Charles Fairfax, deeming the meal, "An insufficient morsel." He disappeared. The Doctor was examining the victims, when he returned, and the Doctor asked who he was, because he could write in High Gallifreyan. The gentleman didn't provide an answer, and instead taunted the Doctor with the unknown knowledge. He then promptly began to steal the Doctor's time, which would have given him his own reality, but Amy Pond smashed the quantum resonator, apparently sucking him back into his hypothetical world. All of the victims were freed. As the Doctor, Amy, and Rory tried to leave in the TARDIS, the control panel sparked, surprising the Doctor, and he described it as the TARDIS having an upset tummy, and that it was nothing to worry about. It was shown, however, that the hypothetical gentleman was the cause, and that he was hiding on the TARDIS.
