I am still puzzle on who would have done it. To me it just makes no sense why Jade would be responsible. Revenge for what? Her husband I don't think slept with Cathy. Derek made me wonder since he took a picture of her in class but what would be his motive? I think I need to play it again because that part came up so quickly that I was like what? I thought Quinn may have done it but then again. Why would she care about a math and English teacher?
Quinn’s motivation would have been to get access to the safe. It’s a bit of theorycraft, but essentially, Camilla is fucking someone (I think Rusty) While he is distracted Riona gets the laptop takes it to the library and posts the CLUCK, while the DIKs panic Quinn tries to get in the safe.
Jocks are one theory but aren’t smart enough.
Tri Beta’s perhaps as revenge for the wedgies.
Jade for revenge for Cathy banking Stephen.
Vinny again to create a distraction to get in the safe. Possibly with Nicks help.
