He is the only person besides Dumbledore and Fred and George Weasley who can exert any control over the poltergeist Peeves; Peeves is terrified of him for some unknown reason, referring to him as "Your Bloodiness" and "Mr Baron".
On je jedina osoba osim Dumbledorea koja može kontolirati Peevesa zato što ga se Peeves, iz nekog nepoznatog razloga, neopisivo boji; obraća mu se s "Vaša krvavosti" i "Gospodine Barun".
