Whatever I said, I chose to fight for you, and chose to fight with me. I didn't have to say anything, we both knew that we'd be free. But now you don't know, the pain I went through to save you, and now, I'm happy this all happened.
Ash Ketchum had once choice, to fight alongside The Fury, and he was forced to choose it. He was forced to wreck havoc in Kalos. He was forced to suffer, only to feel agony in the end. He fought for everyone, but he fought for Serena the most.
He fought to see her once again. He fought to see a smile on her face. He fought to stop the Kalos Region from utter destruction. And in the end, did it pay off? Did he truly fight for nothing? He did fight for something, something that truly wins in the end. He fought for amour.
