Probably not
that much different. But since it seems to be going ignored, I'd just like to point out: notice that Ash's dancing got
significantly better after he danced with Aria, though we admittedly didn't get to see very much of it. I'm not sure what she says in the English dub, but in the Japanese, she tells him to relax. I'm thinking him being tense and uncomfortable (and woefully out of his element) really wasn't helping matters as far as his dancing went. From personal experience? It
really doesn't help, so while it was definitely funny, I did sympathize with Ash. Yeah, and Miette too.
With a skull that thick and dense, those headbutts had to have packed a punch!
Anyways, after Aria told Ash to relax, notice that by the time Serena was about to dance with him, he was doing just fine. The girl in front of Serena sure as hell didn't seem to have any problems with Ash's dancing. Ash even seemed to be somewhat enjoying himself (I don't think it's out of the realm of possibility; ballroom dancing is not something he'd normally go for, but remember that Ash is always down for new experiences, and doesn't think of
anything as a waste of time). Now, if Ash had attended as Serena's date,
and she also was the one to tell him to relax? Well...
...Then poor Serena would probably be the only one to not get to enjoy a round of dancing with him, and she'd be trolled anyway.
But I imagine Ash would probably want to make it up to her somehow. How? Not really sure, hadn't thought that far. If you wanna go full throttle on the fanfic mode, maybe at the end of the episode he'd offer her a dance, which she'd gladly accept. ...Though to be honest, I can never tell when I'm going full fanfic mode or not with this ship. Some of the stuff that has been gifted to the ship at times just sound straight out of fanfiction... the childhood flashback, the date, the cosplay episode, the dance, the second date, the kiss... Before XY started, if you told me Ash's newest female companion would have these with Ash, I would have told you to put down the crack pipe. Yet, here we are.
And of course, if Ash had gone as Serena's date, that likely means her Eevee was cool with going with Pikachu, so Eevee/Sylveon x Pikachu as a side bonus? XD
