Taking Down the Traitor

This AU contains Hero Dabi with fixed scars infiltrating the LoV, it's only mentioned and not a character so far but I'll mention it here anyway.

Aizawa and Nezu have a plan to take down the UA traitor. But how are two completely random objects, a fake knife, twenty copies of the same event from different eyes and a glass supposed to reveal the traitor?
When Class 1-A's homeroom teacher, Eraser Head, tells the class that raiding a rarely-used LoV building will reveal the UA traitor, he gives each of them a plan to follow, a group, and no other context.
Twenty nearly-separate plans on how the day will turn out. Six objectives hidden to the rest of the class.
One traitor.
