Avengers: Infinity War II

(Thor's spaceship was captured by Thanos, who was collecting the Infinity Stones, and one of them was on that ship, along with Loki, who was obviously chained after he was caught again and was about to be transferred to Asgard...Thanos' guards killed almost everyone who was there except Thor and Loki, since they were the only ones who knew where the next Infinity Stone was, but the servant chained Thor so that he would not interfere with them...Loki, taking advantage of the moment, freed himself from the shackles, but did not run away for one reason - to lose his brother...then he decided to play along with Thanos, because he knew that he did not know who he was, so he would believe his every word without question...Loki quietly took the next Infinity Stone from another room and hid it and, with the help of his magic, made a plausible copy that was indistinguishable from the original....at that moment, he was caught by Thanos' guards, who did not see the whole process, but only how he stood at the Infinity Stone as if he was going to take it, and then they brought him to Thanos, who had it on one hand Infinity Gauntlet with one of the stones)
