Considering what it would be like to have to talk to Ron when she really didn't want to, she settled on a different option. "Would it be okay if contacted him and mentioned our conversation?" Because she really did want to get to the bottom of this and she had nothing outright against Percy Weasley.
"You know to try and get him to talk and confirm if there is the connection?" Once they figured that out, there might be more, but right now she would start there. Baby steps.
