>>39845132I don't find it weird at all. I believe trainers step in the way because, what is to say that the Poké Ball being thrown is not in fact jailbroken? There's really no way to tell if a Poké Ball is jailbroken or not, might as well intervene the theft attempt.
In Colosseum, if you attempt to catch a non-Shadow Pokémon, Rui will get in the way and scold Wes, much like the trainer in the mainline games.
