Esmeralda Moreau / Slytherin

Esmeralda sat in the Great Hall during one of the busier times for Breakfast. It wasn't the smartest choice by her to come more later than she had planned, but it was also planned. It was the only time she could tell that a certain Gryffindor would even eat there. What was their convenience was her inconvenience, but it was also their flaw. The gryffindor wasn't very spontaneous and often did things on repeat. Which was easy tracking for someone who wanted to lay a trap.

Too easy.

Grinning as the Gryffindor walked in, right on time she might add as she held the small vial between her two fingers swirling it slightly. It would all be worth it soon. Taking out her wand she performed a simple levitation charm on it as gave it a flick as it turned over into the goblet she also knew the person would take.

Licking her lips she levitated it back to her own self tucking it quickly away in her pocket. Taking a quick glance around to see if anyone had noticed she whistled softly. Almost an innocent whistle some might say.

Reaching over she took a piece of toast and slid it into her mouth. What was in said vial you say? A melted version of the Ton-Tongue Toffee. Grinning she licked her lips waiting for the moment as the goblet filled with the juice of their choice unbeknownst of what was already in there.

In a few minutes as screams erupted from behind her she grinned getting up taking a few piece of toast with her as she walked out of the great hall, still whistling that song.
