Well I dunno then, that's just what I thought was said.
I'm glad Serena is finally capturing her third pokemon, which is hard to believe since we're over 90 episodes into XY now. I don't know why Serena's development in the series is so much slower than all the past main girls, since 90 episodes into each series all the previous girls were already competent battlers with at least 4 pokemon and had already won tons of battles. Serena has pretty much lost every non-Team Rocket battle she has ever been in, and she looks like she's going to lose the tag battle match with Ash/Tierno too.
I guess the writers want Serena to be a waifu for Ash rather than an actual battler. She actually reminds me of the type of female characters you see in other anime who mainly exist to be a love interest for the male lead but not do much else besides that. Practically her entire character is written around her crush on Ash, and her goal is largely just idol fanservice.
I guess the writers thought after everyone disliked Iris that they had to make the next girl loyal to Ash and make her as pretty as possible, but its not enough like with past leads.
