This was one of the more memorable XY episodes for me, likely because I watched a short marathon of the first ones I liked how both Ash and TR were actually demonstrating a bit of their experience and getting straight to business throughout.
Standout moments was James very easily capturing Inkay his trademark method (aw Inkay, as overused as you were, I still think you're adorable).
Also we get more casual interaction with Ash and the Citron siblings. The Clemont tech gag begins. XD
Perhaps the most standout moment was Froakie vs Fletchling, or more the turnout of it. I liked how Froakie was disobedient, but Ash, now experienced with that sort of thing and in touch with his Pokemon, is patient and understands exactly what's wrong (granted Froakie's reasons were far more selfless than the likes of Charizard). What could have been a long arc of turmoil is quickly resolved with one empathetic talk.
In hindsight, it's a real shame how much both of these Pokemon's characterisations got diluted as they evolved. Not only did they have way more quirks but their interactions played not just with Ash but themselves and even the other companions (most blatantly Bonnie here). Fletchling being a mischievous little troll also had potential.
