Yes your right, That's what they said.
It was just an old wound on the foot that they took as proof he was the prince but anyone can have a scar on the foot. the true proof was the jade amulet in the pickle jar that they were looking for. Its a bit confusing cause they jumped on him being the "prince" because of a foot scar
Ahhh, so it was the old, 2 guys who happened to be best friends from the same tiny village happened to have a serious old scar on the same spot on the same foot ploy!
I thought there was a mark on his foot that proved he was the brother. I may have to re-read this.
