I watched the episode and i think that it's beautiful!
I notice that Ash and Serena were very close and in a moment Serena was very shy. Ash said:"What?" and Serena:"nothing*giggled*.
I notice that in the end of the episode Serena choose her goal but I'm not secure about this...(I heard "Satoshi" several times in that moment).
its more like she having interest to see what does performer do, the chances her goal is to be a performer is getting high :/ , which is good i guess if ever this happen, she might travel with ash to next region since theres no contest in kalos region.. (hmm is performer and contest is same or diff? i mean like dawn?)
