I mean, almost everything had to align just perfectly for the events in this game to unfold the way they did. If anyone other than Colette had been the Chosen, Lloyd would not have gone along with them, because he wouldn't have had the same attachment. If anyone but Sheena was sent over to kill the Chosen of Sylvarant, Colette would probably be dead. If they didn't get to Meltokio at the exact moment they did, they'd be stuck there, because they wouldn't have been able to get into the castle. Mithos even says that Colette's mana signature (is that what it's called? I can't remember.) is the closest to Martel's that he had ever encountered. Without Presea, it's probably a safe bet that, if they could even get out of Meltokio, when they came back, Regal would have likely captured them. Or at the very least, he wouldn't join them after that fight, because he wouldn't know about Presea. There are a lot of things like this. I know it sounds like I'm nitpicking, but these aren't really things that bother me, I just thought they were interesting. I see this kind of convenience in a lot of games, but idk if I've ever seen one with this much. Again, as a fictional narrative, I think it's great, and there isn't much of anything I'd change, but looking at it from another perspective makes me realize, not just how lucky they are, but how often they are that lucky.
