Alright, starting off: I thought that the first evolution sequence wasn't gonna revert.
After all Riolu was a happiness evolution, so I had no issues with him evolving just then, but Cyndaquil... just evolved twice. So, that is the only bit that really concerned me at that point.
Yes. I legitimately thought it was just gonna be a normal evolution.

Secondly, I thought the partner was going to have turned out to have been the human from the past when it was all being mentioned, instead of being Mew. Because lets face it, it would have been interesting to have two humans taking down the final boss, or even to fight a human as a final boss. I guess the first Mystery Dungeon counts, though. Just not a final boss :V
