Faced with the intense sandstorm of Route 4, White decides to buy gear to enable them to travel through it. As Black waits for her to return, a card game played by nearby construction workers and a dealer catches his eye.
Black and the dealer go outside and play a game of predicting where a Drilbur will surface. When someone who appears to be a construction worker gets caught in the tunnels Drilbur has dug, the dealer attacks him and reveals him as a disguised Team Plasma member.
The dealer reveals himself to be Grimsley of the Unova Elite Four, blowing Black's mind. Grimsley offers to battle Black on the condition that if Black loses, he must give up what it is most important to him.
Conflicted, Black looks down at his badges.
