>M-muh Yajima said it's canon
Oguro (Interviewer): I haven't watched the episode, so this might be a stupid question, but did Serena's love (for Ash) come to fruition? (Note: This interview was conducted hours before the final episode)
Yajima (Director): It didn't in the episode. I ended it in a way that her love will hopefully come to fruition in the future. Serena told Ash that she's going to improve herself, and then come back to him. Afterwards, she did something that's revolutionary-worthy (laugh). In the middle of production, I added in a scene intended to show them kissing. It's just that I wasn't allowed to have them kissing on screen, so I had Serena's feet "floating" to show it instead.
Oguro: So depending on how you view it, it seems like they might be kissing, right?
Producer (No name): No, it should look like they were definitely kissing.
Yajima: (Laugh) Whether they kissed or she whispered something in his ear, that scene was supposed to be ambiguous.
Oguro: For Pokemon, the XY series is quite the transition. In XY, you guys included a scene where Serena was thinking if she was on a date with Ash when they were walking on the street, blushing and all. The drama itself is quite interesting, but it does make you think how her feeling will be brought to conclusion.
Yajima: I was the one who wrote the final episode, but I tend to put my pen down whenever it's their parting scene. "How should I end it so that it'd be fair for her" tend to be the reason.
Producer: The actual scene differed from the screenplay, after all.
Yajima: That is true (laugh). The scene had her riding on the escalator for a bit, and then she ran back up and kissed him. Naturally, the escalator will take her down again, right? So while she's kissing him, she'll be pulled away. That's the scene that I wanted to make.
Producer: Kids are the main target audience, after all, so among the things we can't do, this series is definitely on the edge.
That's all he said
