Recap / Fillmore The Shreds Fell Like Snowflakes

• Alone with the Psycho: While Vallejo is securing the last presumed target of the Shredder, Francine Bishop's ice garden, the Safety Patrol comes across evidence that phone calls went out from the Bishop household to the members of the Drama Club a day before the shreddings, and the Drama Club was paid off to shred their own fake projects and pretend to be traumatized. And as Fillmore and Ingrid rush to the Bishop household to help Vallejo, they realize that Frank had no way to pay off anyone due to his conspicuous lack of allowance - narrowing it down to Francine, who upon being confronted about it then admits to wanting revenge on Vallejo.
• Cain and Abel: Francine Bishop's the Cain to Frank's Abel, creating a fake Shredder and trying to ruin Vallejo's career in the Safety Patrol.
• Conscience Makes You Go Back: Frank Bishop originally declined to help the Safety Patrol beyond a small tip-off to the Shredder's next target. He changed his mind after thinking on what Fillmore and Ingrid said to him.
• A Day in the Limelight: For Vallejo as his past before becoming Chief gets focus here.
• Engineered Heroics: Fillmore and Ingrid find the emergence of a serial criminal that only Frank seems capable of stopping a little suspect. And it is. Just not for the reasons they think.
• Everyone Has Standards: Frank resents Vallejo for not sticking up for him after the gazpacho incident, but when he learns his sister is attempting to sabotage Vallejo's career, not to mention that she's doing so in a way that could have killed him, he's horrified.
• Explain, Explain... Oh, Crap!: Just when they seem to have enough evidence pointing to Frank as the Shredder, Fillmore asks Ingrid how Frank could pay the Drama Club to help set things up if he doesn't have an allowance, which causes them to realize which other person matches everything they have.
• Formerly Fit: A subdued example, but Frank appears to have gotten a bit chubby since he was forced out of the Safety Patrol since he apparently doesn't give a crap about doing anything anymore.
• Hypocritical Humor: Cheerleader Cheri Shotwell claims that she's passionate about saving the environment before she promptly covers her head with a cloud of hairspray.
• It's Personal: Francine Bishop, the master Shredder, orchestrated the supposed string of serial shredding by getting her friends in the drama club to wreck their superfluous projects (one was fake, another was for extra credit). Her reason was to give Frank motivation to go back to being a profiler again after seeing him rot away for so long, and to create a case that would interfere with Vallejo's renewal as chief out of revenge for wrecking Frank's life.
• I Want My Mommy!: Lorenzo, the first victim on screen, is left pathetically babbling "Ay Mamacita" over and over again as he lays in a pile of his shredder petition papers. He was just pretending to be traumatized.
• Large Ham: The Shredder's victims are left in traumatized heaps sobbing over their destroyed projects by the time the Safety Patrol finds them. Turns out they're all in the drama club and were overacting their supposed angst after destroying the projects themselves.
• Laser-Guided Karma: Francine's ice garden ends up destroyed when Vallejo commandeers her snowplow as she's about to run over Fillmore and Ingrid with it (albeit by accident while blinded by blowing snow).
• My Greatest Failure: Vallejo looks back on how he didn't step up for Frank when he was removed from the Safety Patrol as one of the worst things he's ever done.
• Never My Fault: Combined with Villains Want Mercy, Francine tries to guilt Vallejo into "atoning" for what happened to Frank by letting her go once she's caught... He doesn't, but not even Frank would have.
• "No. Just… No" Reaction: Fillmore's response when O'Farrell misunderstands his confusion towards his latest Shredder sketch, describing it like an oyster without its shell.
  O'Farrell: Are you telling me that the perp is some kind of mutant oyster?!
  Fillmore: N-no. No, Danny, I'm not.
• No Sympathy: Fillmore bluntly makes it clear he doesn't feel sorry for Frank despite how unfairly he was treated, since Frank only desires to wallow in self misery instead of moving on or doing something with his life. Even admitting that Fillmore is right.
• Opinion Override: After Frank confronts Francine about her plans and makes it clear he doesn't want this, she locks both him and Vallejo inside one of her ice sculptures and tells him he'll thank her for it later.
• Plot Allergy: What got Frank Bishop kicked off the squad was a perp who suffered an extreme allergic reaction from being doused in gazpacho (which Frank threw on him to make him stop). The kid's parents threatened to sue the school unless Frank was removed from the Safety Patrol.
• Properly Paranoid: Inverted. Vallejo's refusal to believe Frank is the culprit ultimately turns out to be correct.
• Red Herring: As the episode starts reaching its climax, it leads to the conclusion that Frank Bishop is the Shredder, who is now approaching ominously behind Vallejo with the shredder in hand. Then Fillmore and Ingrid realize that Frank had no way to pay the drama club actors to commit the shreddings... and at that moment it cuts back to Frank accusing Francine of being the Shredder and that he found the shredder in her room.
• Small Name, Big Ego: Principal Folsom's apparently such an egotist the school's drama club is doing a musical about her life story.
• Take Our Word for It: O'Farrell's hideous sketches of what the Shredder supposedly looks like are only shown to the Safety Patrol, who can only react in concerned confusion by how bad they are.
