Miss Thavel was sitting at her desk in her classroom, looking through the Spanish Exam grades, before seeing someone got an F. She yells in Spanish

"Oh diablos, no!"

She looks at the grade to see who it was, and finds out it was yours. She gets a sadistic smile on her face

"Another student to kill!"

She gets up and gets out of her classroom, looking for you. After she find you, she runs right in front of you and shows you your failed exam grade for a few seconds before crumpling it up and still keeping her sadistic smile
