Luther trains by himself that night, but to his disappointment there are no visible results. A man bound from head to toe in a mysterious location is confronted by a bald man, identified as the Librarian; he approaches and tells the bound man they've found a candidate. Luther, meanwhile, has gained inhuman reflexes and speed, as seen when he catches a falling dish. At school, Pete pushes Luther into Petra, a girl who he's been pining for. Later at P.E. Pete is hit during a game of dodge ball; a bully, named Paul, takes a cheap throw at Luther, who isn't seemingly paying attention. Luther's reflexes kick in and he catches it and throws it back with enough force that it's later revealed he broke Paul's nose. Aboard a ship in an unknown location a single crewman is hunted and seemingly killed by the Librarian. Back at school, Pete and Luther are cornered by Paul and his friends in the bathroom; Luther, at first, takes the beating from Paul until the latter mentions Petra. Luther responds with a single punch that shatters Paul's jaw and disgusts everyone else. [3]
A few weeks later, Luther returns to school after being suspended for the punch. Paul again tries to pick a fight. Uncharacteristically, as he stops Paul from going after Pete, Luther starts having visions of him starting a school massacre with just his bare hands. After relaxing and letting Paul go on his way, he begins to notice he is starting to see people as their musculature, but it appears to stop. Petra approaches, and after some talk that makes Pete leave her alone with Luther, Petra admits she mutually has feelings for Luther. Later that night, Paul is attacked and killed by the Librarian, who has already slaughtered his parents. Luther is training when Petra comes into his room, catching him in just his underwear. An unknown amount of time later, Luther recounts the night with Petra to Pete as they go to a liquor store, which gets held up. Luther uses his abilities to stop the robbery and Pete declares him a superhero. [4]

It's shown later that the robbers that Luther stopped are killed by the Librarian, when Pete talks to Luther about it they're interrupted by Petra, who's been physically abused but is hiding and being evasive about it. Luther, in his frustration, visits the guy who was defended by the woman the previous night and beats him half to death. After throwing the beaten man across the room, the Librarian enters and tells Luther to finish it. [5]
