Dragonite apparently doesn't yet trust Iris's judgment against Pokemon it sees as a threat (this is just going from what I have heard. Like I said, really want to watch the subs before talking about those 2 latest eps).
So when facing 2 strong fully evolved ice type Pokemon it does it's own thing.
Then it faces a mid stage ground/ dark type and is OK with Obeying ... until it suddenly evolves, making Dragonite spin into a rage.
She failed at what exactly?And she failed, but did that actually cost her anything? No. Were there consequences? No. Not for the first two rounds at least. The impact of the loss is greatly diminished by the two wins she didn't deserve.
Getting into sync with Dragonite? There's no real failing at something that's really just gonna take time to happen, the most she can do is make sure they battle together often enough to give their connection a chance to grow.
And WHAT consequences are you talking about? Please give me an example of a reasonable "consequence" to her using this tourney as a chance to train/ connect with Dragonite. Are you upset that she made it 2 rounds with Dragonite against Pokemon that Excadrill could beat? Are you upset that Dragonite's not like Charizard and actually wants to win battles on it's own instead of just saying "... Ef Off, I'm taking a nap"? Are you upset that they didn't kick her out of the tourney after the first win?
What kinda "consequences" did you want besides her not winning the whole tourney? And who cares if she won 2 battles in this tourney with Dragonite? That thing's clearly too strong to be shot down by any of the present trainer Pokemon which is why it had to be spun into an uncontrolled rage to be knocked out.
