Actually I think this would be an interesting take on a character... I would LOVE to see Serena in a kind of video diary/filmmaker type of role! Instead of strictly competition-based (like contests/battling) I think I'd really like for her to explore the journalism/global aspect of Pokemon thing. We've already got two dedicated battlers (Satoshi, Citron) on the team and one character without a set goal except to have fun and learn (Eureka) so for Serena to take a more "passive" role and make movies would be totally fine with me. I think it would add a real edge to her character and make for some really entertaining episodes.
