Pikachu doesn't appear to have a care in the world as he dashes up to the waterfall, letting out a victorious 'Pika!' when he he's the clear winner of the race. He pauses though as something doesn't seem quite right.

"Okay, you win." Ash concedes defeat as he makes it to the waterfall and than pauses, noting Pikachu's stance. "What's up, Pikachu?"

Both take a step back once the man reveals himself, Ash's good mood vanishing in an instant.

"What are you doing here?" He demands, shifting into a more battle ready stance. Pikachu, following suit.
