How does Percy get even with Gabe as they are loading the Camaro?

Percy Jackson gets even with Gabe Ugliano by using a trick to turn the tables on him. As they load the Camaro, Percy uses a little bit of magic from the gods. He causes Gabe's favorite possessions to be encased in concrete, making it impossible for him to enjoy them. This act serves as a fitting form of revenge for Gabe's abusive behavior towards Percy and his mother.
