Remember that he already suspects her of being one? He just brought it up, but yes. They should have some kind of effect when close to other magicians that can give them away, perhaps scent is one of it. Or perhaps the prince is just manipulative trying to see their reactions to confirm his suspicions
bruh, didn't u see she cut herself with the roses thorns? Of course as a purifier her blood is diff that's why maybe the cause, why the prince sense it when the rose petal with the blood flew across him
It was stated that to be purified you need to have a physical contact (the "deeper" the contact the greater the purification) so either just touching hands kissing and even drinking their blood can purify magicians. And since the girl got her hand injured by the rose thorns i guess the smell of her blood is different since she's a purifier and since the prince is also a wizard he noticed that scent thingy from the rose petals with her blood on it hahaha
Are we supposed to assume the scent is from her ‘purifier’ status? Or do we not know yet??
