Canon in the long term certainly. Amour is probably the closest it's ever going to get to canon in the meantime. But my point was that your proposal for Serena's cameo wouldn't work unless Ash was leaving for good.Well yes. Amour (or any ship for that matter) can only be canon if his adventure ends.
I'd have to argue that they really didn't ease up on it in XY. Perhaps you could argue that Serena was far more intense than anything prior but he was still incredibly dense in XY. There wasn't a huge difference in his behavior towards Serena compared to any of his previous friends.He was comically dense in other series. But in XY, it seemed like it they eased up on it significantly. While he may have been oblivious to certain things, he still seemed very tuned into how Serena was feeling.
So in Party Dancecapades, Ash seemed out of character in context to the rest of XYZ.
