Loki Season 2's fifth episode, named Science/Fiction, has ignited fan speculations due to a note reading "Sacrifice: Something must be given up." During the episode, Loki, played by Tom Hiddleston, time-travels through dying timelines to reconnect with his allies. He meets fan-favorite O.B., who's a struggling science fiction writer in this branched timeline. Viewers speculated that the sticky notes on O.B.'s wall, serving as the plot of his novel, are actually hinting at significant events in Loki's season finale, particularly a potential impending sacrifice. The season's finale will release on Disney+ on November 9 at 9 p.m. ET / 6 p.m. PT.
