When Otto said he was coming, Trouble was sure that it would be absolutely insulting if she didn't give him a proper welcome, so she'd managed to transfigure a rock into bucket, fill it with water and stick it up in one of the trees with a trap spell. Once he walked in the right spot, the thing would go off and she would be laughing her ass off.
Once that was set, she waited, her arms crossed as she looked out onto the great lake, enjoying the sight of the water, even if she had no intention of getting near it. No way in hell did she want to ruin the dark purple jacket and black jeans that she wore today.
Gwen heard him call out to her, and then pointedly ignored him. She didn't respond when people used her real name. it was trouble or nothing. The only people allowed to call her Gwendolyn were her father, her birth mother and her future lover, all of whom Otto was not.
Of course, then she heard her trap tripped and turned to watch as the the bucket tipped and the water soaked him. Grinning she stepped towards him. "Yep, you are here and you are soaked."
