*The reflex is childish, it's hurt. A fluttering of confused limbs and strange signals and barely-covered-territory. Barty has been pushed away all his life. By his father, by the neighbour children, by the oft used phrase, "Not now, I'm busy". Regulus had always been the one to pay him the courtesy of attention and in all their disagreements he's never once been pushed away - not properly, not physically. But exceptional measures breed exceptional results - his tangle of appendages reorient themselves, gain energy and force and shove back with a violent and crestfallen shock.*
