Karen looked out the window at that moment and seen a buxom girl jogging down the street.She smiled "how about the jogger out there".
Jon turned to look out the window only to see the back of the jogger running past his house. He thought for a sec. then why not as he pulled the trigger.
One sec. Jon was in his room the next he was in the jogger as his/her hands went to her breasts he realized he did not have the gun, how was he going to get back into his house to change back. Looking up at his window he seen Karen leaning out the windo with a smile on her face and the stone in her hand.
