"Use the stone to get your mom back and then wish the aliens away," Karyn said. "Who knows what they're up to?"
"Yeah, okay," Jon said. "I wish ..." But before he could finish, his bedroom door flew open (and then off its hinges) and his mother (his fake mother) walked in and shot some sort of blue beam of light at him (Jon figured it was some sort of energy pulse weapon - he watched a lot of sci-fi movies). The stone flew out of his hand and fell under the bed, as he involuntarily grabbed his arm. Whatever that beam did to his arm, it hurt like hell.
"What's going on?" Jon's sister Zoe asked, panicking, as she ran into Jon's bedroom. Her eyes were wide, seeing all the damage that was done to the bedroom door.
"Zoe, get out of here!" Jon yelled.
