There was a gust of wind as Sam roared past him, all muscle and power rendered invisible. Really? He'd sacrifice the dog for his own life? That was cold.

"Apparently you do."

He turned after him, letting the dog go just as easily as he had taken her hostage, and whirled into shadow, reappearing in the doorway of the next room. He hadn't predicted invisibility in Sam's list of powers, and it was forcing him to think on his feet, but the moment the glass smashed he was throwing his hand up, and he caught the owl just as it finished transforming, wings wide.

Trapped in telekinesis, pressing in on all sides, transformation as much as movement were stopped dead. But he couldn't exactly pick apart a power when it was in the head of an owl, which caused a whole host of entirely new problems, such as how to get him to change back.

A flick of his hand, and the owl was flattened against the wall behind him, and then as he found his place between the wall and the window, he brought knives into play from the kitchen, driving one five inch blade through each outstretched wing, at about his own eyelevel, working on a hunch that the pain would make Sam change back. He'd barely even worked up a sweat.
