Yep, and Bonnie meanwhile will be cheering for his brother. (self-explanatory). Although, it would be funny if she decided to cheer for Ash instead xD, but I don't see that happening.
Indeed, that would be funny if Meyer decided to make a comment about Serena and Ash looking like a couple, Bonnie will probably contribute to his discussion too.
I'm not sure if this might happen, but it would be nice if at the end, Clemont will reserve a place on the top of Prism Tower and they admire the view. Then you'll just have a camera shot of just Ash and Serena leaning over the railing admiring the view, it would be nice to finish off the episode.
Can't wait for that episode to air!
