So you know how Thursday night all those sudowoodo disappeared having been captured by Rockets? Well Duncan and Shorty and a bunch of other Rockets from Saffron were flown in to help! And. And Duncan and Shorty proceeded to miss the flight back. Lynea wasn't pleased to hear this.
In which Duncan calls Lucas to inform him that his marowak was probably kidnapped as a Cubone.
Relevant info: Duncan has been tracking down the names of buyers and calling them when he could dig up contact info. He called Lucas's home and left a message with his family, and this is Lucas calling him back.
