After a run-in with Sister Michael leaves them worrying about their GCSEs, the girls attempt to break into the school to see their results early. Granda Joe has adopted a cat named Seamus.
Tropes
- Armor-Piercing Question: The inspector's interrogation loses a lot of steam when Erin pointedly asks him how many Catholics are in the RUC, and he's forced to admit there's only three (if one counts their Jewish officer).
- Artistic License: Liam Neeson's cameo character is consistently referred to as an inspector despite his clearly wearing the uniform of a chief constable.
- Atrocious Alias / Lazy Alias: The computer thief claims his name is Hans, as in Hans Christian Andersen. His partner thinks this is a bad fake name and grills him about it, but the Derry girls don't notice.
- Disposing of a Body: Parodied Trope when after his new cat kills a rabbit, Joe decides to dispose of the body to protect the cat.
- Explain, Explain... Oh, Crap!: It's only when the gang help the "workers" get rid of the "used" computers that something hits the gang...Clare: Only...weren't those computers relatively new?
Erin: I think they might have been yeah.
Clare: Right...so...isn't it a bit weird two men we've never seen before just sort of took away a load of really expensive equipment in the middle of the night?
Michelle: What are you getting at, Clare?
Clare: It's just that...now...on reflection...I'm slightly worried we might have accidentally helped burgle the school.
[cue police showing up] - Good-Looking Privates: Upon arrival at the station Michelle immediately starts flirting with the constable.
- Insane Troll Logic: The RUC has 3 Catholic officers—one of whom is Jewish. For their intents and purposes, "Catholic" means "not Protestant."Erin: If your organisation isn't prejudiced, Inspector, then you won't mind telling us how many Catholic officers are serving in it at this time.
Inspector: I think we're losing sight of who's questioning who here, girls.
Erin: How many?
Inspector: [stammers] Well, if you count the Jewish fella from Ballymena, three.
Erin: [incredulous] In the entire police force, you have three Catholic officers, and one of those officers is a Jew? - It Amused Me / Troll: Sister MichaelClare: You said we failed!
Sister Michael: I didn't say you failed. I implied you failed.
Erin: Why?
Sister Michael: Bit of a slow day. - Kansas City Shuffle: The girls and James get suckered into one by the two computer thieves, who act like they're school employees and demand to know why the gang is there. Once the Derry Girls are assured that they're not going to be get in trouble, they cheerfully help load up the thieves' van with the contents of the computer lab.
- Mundane Solution: The gang are thinking about ways to bypass a lock. Orla is the only one who bothers to try the door, and discovers it's unlocked.
- Old Windbag: After ruling out their parents (who will kill them) the girls decide to beat the police at their own game by bringing in someone who will wear them down: Uncle Colm.
- Profiling: When the gang are brought to a police station, they immediately start freaking out and Discussing this, because the RUC is known for profiling Catholics. Subverted Trope, because they're not actually being profiled here. They witnessed a burglary and being questioned about it is perfectly reasonable.Clare: We're Catholics, for Christ's sake! Have you never seen In the Name of the Father? They'll think nothing of sending us down for a crime we didn't commit! We'll be like the Guildford Four, the Birmingham Six!
- Selective Obliviousness: Joe flatly denies that Seamus has been the one taking down small animals in the local vicinity, despite clear evidence that he has.
