She did. She started doing it when the relationship first became public. It becomes more noticeable when she moved to the UK. Harry was twelve when his mottler died. He will remember mannerisms. He may not have realized it was deliberate on her part but it will have triggered the fear that the same could happen. Meaghan certainly fed that fear. There’s a high probability that she was telling him she was afraid of being subjected to that level of media attention. She wanted that, to mind, and was trying to create it but for Harry it’s something quite different.

Edit: Corrected Harrys age.
