Question: In the opening credits of Arrival and most subsequent episodes of The Prisoner, Patrick McGoohan/The Prisoner/Number Six walks into a government office and resigns his post. He returns to his house. A man, dressed like an undertaker, pumps gas through the keyhole. He falls unconscious and revives in "The Village." My questions? Is there a "knockout gas" that would render somebody unconscious like this? If so, after inhaling the gas, for how long would they remain unconscious? We never know where "The Village" is, so we cannot know how long it took to move Patrick McGoohan there, but how would they keep him unconscious until they got him to "The Village"? As soon as he comes to in "The Village" he seems 100% fit and alert and immediately begins to explore his new "home." Wouldn't he have a splitting headache, and be dazed, confused and disorientated after being unconscious for so long and then waking up in such a strange place?
Answer: Carisoprodol, Cyclobenzaprine, Ether, Chloroform and Nitrous Oxide have strong sedating effects. As for waking up alert, once the effects of the gas wear off, he could wake up as thou had a long sleep.
