I really can’t, but presumably he’s fine with her repeatedly implying that’s exactly what her parents did.Could you really imagine Big Dave the town trumpet standing by silently while all this is apparently going on? Unless he was complicit in it (which I doubt but sadly does happen) then he would be the first at the police station door.
I truly believe if her parents, in particular Big D, actually put their foot down and told her to stop repeating that, calling their foster kids feral etc she would. But they aren’t and that’s very puzzling to me.
