A Dash of Vanilla

Tosh, Owen, and Gwen stepped into the Hub, only to find it looking as if a blizzard had hit it (In fact, Owen briefly wondered if that is exactly what happened). Things were scattered everywhere. Ianto had somehow managed to fall asleep against the wall while trying to clean up. Tosh gently woke him up.
"What happened here?" She asked concernedly. Ianto glanced at them tiredly.
"Never put vanilla in Jack's coffee," he said. "It makes him hyper."
