Sarah gasped. 
"Stop them!"

She ran outside. she had returned Alakazam to his pokeball. Gengar floated above, looking around from the air. 

"Rapidash!"
Sarah stopped the very fast horse pokemon. She got onto her back since she was much much faster than a car, and seemed just as willing to go after him as the other pokemon. 

Sarah was prepared to give chase, or track him down, whichever came first.
