I seriously couldn't give two shits about how that Dragonite was caught right before the tournament, or how strong it is. The point that I'm going to take is that Iris got a new addition to her party, which is a good thing (since that's about only her 4th poke in nearly 2 years). I think that, with the way how the series has advanced so far in general strength, that a Doryuzu that rarely battled since the Don Tournament, a young Kibago with powerful top level moves and a lazy Emonga with a weird Volt Switch...Iris would be a fucking pushover in this Tournament!
I'm glad to see that she has a powerful new dragon to not only complement her main objective (indirect character development FTW), but to get her to put up a bit more of a fight in the next episodes when this World Tournament...Young Tournament...Whateverthehellitscalled Tournament goes underway.
So really, I don't see what the fuss is all about and I don't really care about it. This is my approach towards the news that Dragonite was caught.
