Isabella: Mayor Kaylee, I have something important to tell you! (Backstabs you)
Blanca: (reveals self and removes Isabella mask) "You're dead." (Puts on a mask of you, takes your form and runs off.)
Cadence's love will give Shining Armor strength. And bring about a Heart Beatdown that destroys the Chrysalis Ring you were wearing. Thus, you're exposed and sent to prison.

Turns out that person is allergic to peanut butter and the person didn't know it, so that killed the person too.
