Saw that episode a long time ago and I horribly remember the opening scene that during a thunderstorm (and probably raining heavily), wild Swablu and Altaria cuddle each other in a tree, gets struck by lightning and all the Swablus and Altarias fly away, leaving behind one lone Swablu that fears flying and that Swablu injures its wing in the process. I was feeling sad seeing this but my favourite part is when Max uses 'magic flying powder' to trick the Swablu into flying. I was sort of relieved that the Swablu returned to the other Swablus and Altarias but also disappointed that May didn't catch it because she had developed some deep bond with it during the ep.
