Ash Ketchum encountered some Team Yell grunts while on route to his match against Marie
for their Hyper Class Battle. However, in an attempt at making
Marnie win a walkover victory, Team Yell feeds him misinformation regarding the venue of the match and sends him to Spiketown, where he encounters Marie's older brother and Spike Town's Gym Leader,
Piers.
Piers drives
Ash Ketchum to the real venue on his motorcycle and
Marnie got mad at them for making Ash get the wrong venue.
