A friend asked me to answer this question: Who wanted to poison the intruders with cyanide?, using the article: Renton wakes up beside his former lover, Hannah. Three men break into his bedroom and, when Renton breaks his neck while escaping, he wakes with a start where he was just a moment earlier. The men break in once again and bind him and Hannah to chairs in another room. Their leader, Father, says he represents a rebel group known as the Bloc and demands Renton surrender money or "scrips" that he had stolen from their rival organization, the Torus Corporation.
Father and the two other men, Sonny and Brother, leave to eat in another room and Renton is able to cut himself and Hannah loose. He explains that he built the ARQ, a working perpetual motion machine, while working for Torus and then stole the machine. Hannah urges him to comply with the men, but he tries to escape and dies. He wakes with a start back in bed with Hannah, only to relive the same scenario. This time, after freeing the two of them, he asks Hannah to help poison the intruders with cyanide gas. The plan fails when Hannah reveals that she is a member of the Bloc. Renton surrenders the scrips and then Sonny shoots him.
In the next iteration, Renton questions Hannah about her past before freeing her. She admits that she grew to resent him after he abandoned her to Torus, who tortured her. Though he does not trust Hannah, Renton and Hannah work out a deal where they will split the scrips after using the cyanide gas to force Father and his group to stand down. Once they have the three men captured, though, Renton reneges on the deal, demanding that Hannah abandon the Bloc and come with him. Hannah accidentally shoots Renton in an ensuing scuffle. When Renton and Hannah wake up together, she can now recall the previous iteration. Renton theorizes that the ARQ is causing a time loop. Eventually, Sonny reveals himself as a Torus mercenary and kills everyone., what would be the answer ?



Renton
