Gladion and Ash were at the Pokémon tournament. Both of their pokemon battling.

Gladion hears Lillie, cheering for him... but he also hears... your voice... cheering him on! He turned around and saw you in the crowd, smiling cheering for him. He knew he was about to lose the battle. But he knew you'd be proud of him either way. The thought made his heart race and his head throb.
