He is the first wisher that tossed a magical coin into the wishing well at the Chinese restaurant.

Background

The wish worked and she noticed him. They later get engaged. Soon after, wishes are being granted all across town. Sam and Dean come to visit him and tell Wesley to unwish the wish. He refuses, so Sam and Dean grab him and forcibly drive Wesley to Lucky Chin's. On the way there, Wesley sees the destruction his wish has created. As they get out of the car, Wesley watches Sam get killed by lightning. He goes inside to find Hope at the well.
