Episode started of kinda subpar in beginning, but through middle picked up and became very good. I enjoyed in Gible mischief and funny behavior. Biting Axew head, making holes all over the town causing chaos left and right not being able to adapt to new surrounding.
Iris trying to understand its feelings and thoughts was endearing to see with whole scene of climbing on clock tower almost falling of to approach and save small dragon being admiring. She once again lived up to impression in coming of agile and athletic character. Which payed of in end giving us insight in how Gible got himself to end up in Blackthorn city(taking nap on a tree and from what it seemed accidentally ending on Scarmory back landing in town).
Encounter with Clair was pretty interesting and battle between Druddigon and Dragonite was easily highlight of episode imo. At one moment you could even get impression how Dragonite was going to win, especially when Iris sorted her thoughts deciding to connect to her pokemon feelings and inner sttength working like one. Which was definitely worthwhile invoking in Dragonite unused strength starting to overbear Clair Druddigon with thunder punch and dragon rush smashing it into the ground.
Even thoigh it was just one on one battle, intensity and lot of emotion going there made it exciting.
In end Dragonite still lost, but this was actually positive thing to me. Because it revealed how Iris still has lot to learn in becoming true dragon expert earning right to get title of dragon master assigned to her. She showed remarkable improvement but also through this episode revealed how optimal synchronization between her and dragon types haven't been achieved yet in fully understanding their feelings and internal fears or desires giving space for improvement. In realizing how to use them to maximum potential.
Gible capture at end was like icing on the cake rewarding both to Iris character and her fans making new friend and fellow partner on her journey bursting with happiness and confidence of becoming famous and recogniozed dragon expert eventually. Even more so when seeing Raiquaza gliding through sky.
They've all been very close or are currently working towards it but I mean that Misty, at her place as a respected Gym Leader of the Curulean City is what you can consider a "Water Pokemon Master" at least in some form.
Misty didn't came closer toward water master dream, let alone achieved it being in same position like Iris.
Whole reason Misty left gym was to pursue dream,several times stating how she wants to become worlds best water pokemon trainer/master.
So how exactlyy being gym leader before meeting Ash leaving position to pursue water master dream just to later take it over due to sister laziness and need can be considered achieving or coming closer toward her career?
Truth is it cannot.
Misty showed interest in E4 Lorelei wanting to become skilled one day like her as renowned water expert in world , with dream of becoming strongest water trainer entailing to reach levels of E4 trainers(best mono trainers in world/in games called type masters)or even champions like Wallace(possibly strongest water user so far). With her goal showing to involve traveling, entering tournaments, battling other water experts and learning how to understand their full power by exploring on various species and places(like Ash dream involves).
In Whirl cup episodes, it was further proven how gym has very little conections to Mistys goal.Prof.Elm himself confirmed in "Around the Whirlpool" followed by dialogue from sea Priest Maya how winner of Whirl Cup wins title Alpha Omega of water types,by which water masters(sea heroes) in past used to be called, classifying prestige water competitions as tasks which are needed to be fullfilled in order for someone to come even close toward this goal.
At best gym can serve as somekind of "stepping stone",but for all reasons stated above goal of becoming water master cannot be accomplished by being gym leader not being nearly enough.
