I think Ron is spying or Harry.
I hope both Hermione & Harry drop Ron as a friend.
It would have been nice if Harry had clamed any other LOrdships while at Gringotts.
It is implide in Canon Harry is the heir of Griffindor and become Lord Griffindor, as well as become Lord Slytherin, as Harry as a child removed Tom Riddle's Spirit from his body, ans defeated him again two more times at Hogwarts. As Harry is lord to two of the Hogwarts Fonders, Harry should own Hogwarts.
At this point in time, Ron is simply a 13 yr old kid who has a smart friend and a rich friend. He's a bit jealous of both, but they are his friends. I'm not planning on doing any Ron bashing.
As for Harry, I have enough planned for Harry that he wouldn't have time for any other lordships. lol
