>>35053394I wonder if they didn't have her capture it for two reasons:
1. Back in the earlier seasons of the anime, dragon pokemon were never on the main cast. It seemed like one of those types a main character would never have. It was the same with dark pokemon at first. This of course changed when Ash got Gible in DP, then Iris, etc....but back in early Hoenn it was something that never happened.
2. I wonder if this was a way for the writers to have May experience releasing a pokemon without capturing it. May never released any of her pokemon, but the way she said goodbye to Swablu is very similar to all the releases we had in the series for other characters
