Well maybe it was the angriest he had seen her up to that point since the Andrew settlement came afterwards I believe. Or maybe this aid didn't see a whole lot of her, so didn't have much context of previous interaction. Or maybe she just managed to keep her emotions in check most of the time around her staff, but no longer had her beloved Phillip around to pout out her emotions too. It really doesn't matter, does it. What matters is that, once again, her idiot grandson hurt her and her legacy deliberately. And she demonstrated her disapproval by not backing him up when he threatened the BBC - not a tabloid, but our trusted, lefty, public interest broadcaster - with libel.
