It was easy. So easy.
Evans and Lewis were like sitting ducks for him. When he used legilimence on them he made sure to take a couple of interesting notes. Like the girls they were interested in, and their schedules.
So when they got off the train at Hogwarts a letter waited for Evans on his bed.
Dear Orson,
Some friends and I are sneaking out to Hogsmeade tonight. I would love it if you came. Meet us at the girls bathroom on the second floor, third corridor at 10pm. XOXO - Susan
P.S. Please bring your friend Lewis, Daphne thinks he's absolutely dreamy.
Tom only had to wait in the stall. When he heard footsteps he stood in a dark corner as he watched his prey approach. If getting them there was easy, petrifying them was easier. Before they could draw out there wands they smashed against the tile.
He stepped over their bodies and approached the entrance.
Open he whispered in Parseltongue. He lifted his wand and dragged them both to the entrance.
They dropped like rocks to the bottom, he took no care to pad their fall. As he descended he surveyed their injured petrified bodies that resembled broken statues.
He remained impassive as he magically bound and levitated them deep into the chamber.
