The Sarah Jane Adventures/Recap/S1/E05 E6 Warriors of Kudlak

Luke is still struggling to find his place, not understanding the behaviors of other kids. Clyde brings him to Combat 3000, a laser tag chain that has just opened, to teach him the importance of games.

Sarah Jane and Maria investigate the disappearances of children across England, linked with brief storms. They discover that the freak storms occurred as a reaction from a teleportation device, which all occurred in the vicinity of branches of Combat 3000. They take their investigations to the laser tag center (read: sonic and enter and go poking around) and are confronted by the manager, Mr. Mark Grantham. They discover that he and an Uvodni (a humanoid, insectoid alien) called Kudlak are abducting the children for an unseen "Mistress" to turn them into an army of Child Soldiers against their enemies, the Malakh. They are too late to save Luke and Clyde, who have been transported to the Uvodni craft in orbit and are trying to rally the other kids in an escape.

Various sci-fi shout-outs are made and various anvils are dropped. Luke wires Clyde's mobile into the craft computer system and accomplishes feats of tech that would make the Doctor proud. Sarah Jane and Maria trade off being generally awesome in confronting, escaping, and later capturing Grantham, forcing him to teleport them to the Uvodni ship where they and the kids confront The Mistress and her troops.

Tropes

 * AI Is a Crapshoot: The computer.
 * Anti-Villain: Despite his modus operandi, General Kudlak is one of the more honourable antagonists Sarah Jane has faced. He takes no genuine pleasure in his actions but commits them to ensure the Uvodni aren't crushed, and desperately desires peace.
 * Child Soldiers: The aims of the Mistress and the Uvodni.
 * Continuity Nod:
 * Sarah Jane mentions her UNIT training in this serial.
 * The Slabs from the Doctor Who episode "Smith and Jones" are in the employ of the Uvodni, minus all the leather.
 * Cool Old Lady: Sarah Jane, as usual. Grantham even begrudgingly calls her a 'cool old bird.'
 * Getting Crap Past the Radar: Sarah Jane makes what might be a Prison Rape joke.
 * Go and Sin No More: Sarah Jane to Kudlak.
 * Heel Face Turn:
 * YMMV: Humans Are the Real Monsters: Unfortunate Implications for a kid's show, the Uvodni are kidnapping human children because they are one of the most aggressive races in the galaxy, as evidenced by the many wars that humans fight and war games that children play.
 * I Just Want to Be Normal: Luke
 * Karma Houdini: Discussed. Grantham didn't stick around after sending off Sarah Jane and Maria, but they implied he would get what was coming to him 'eventually.' And for what it was worth, they did get a chance to beat up on him, see below.
 * Little Miss Badass: Maria electrocuted Grantham. Nothing fatal, but she succeeded in dropping him while he was holding Sarah Jane at gunpoint for the second time that episode. He should have taken the hint the first time around, when Sarah Jane shorted out his comm device with her sonic lipstick.
 * Proud Warrior Race Guy: The Uvodni.
 * Shout-Out: Lots. Maria mentions Planet of the Apes, Clyde mentions Captain Kirk and Obi-Wan Kenobi.
 * Grantham says 'A galaxy far far away' and when the kids are on board the ship, one girl says "That's no moon."
 * Smug Snake: Grantham.
 * Techno Babble: Sarah Jane has to translate for the kids whenever Mr. Smith is guilty of this.
 * War Is Glorious vs. War Is Hell
