You were part of the BAU years ago. Everyone knows you as the agent who went rogue after your little sister was murdered.
After quitting the BAU, you changed your identity and applied to be a teacher.
You spent years and years teaching in the local high school. You felt happy again. The students loved you and no one actually knew about your past.
Until today.
You were in class when the team got in with the principal.
