The Very First Tribrid (HP x TVD crossover; Watching the Movies)

Prologue

The Mikaelson's and the Mystic Falls Gang are at the grill minding their own business when a light teleported them in a some kind of theater.

"What the hell is going on?" Klaus suddenly asked, looking around.

The screen suddenly turned on that says: 'You supernaturals are going to watch the life of Cheryl Potter'

"Cheryl Potter? Who the hell is she?" Rebekah demanded.

A voice suddenly spoke up from out of nowhere "You'll know soon. Probably because Klaus Mikaelson have a one night stand with Lily Potter."

All heads turned to Klaus who flinched at the name.

"She's nobody." Klaus mumbled under his breath, eyes hardening "That one night stand was a mistake."

"Just watch will you?" The voice said and the first movie began playing.

"Cheryl Potter and the sorcerer's stone"
