One thing about the last episode that was f****** retarded was Reign hitting her with a piece of concrete hard enough to hurt her, but the thing didn't break. Based on literally everything else we have seen on the show, Kryptonians are much, much tougher than concrete. Hell, in that same fight, they were smashing through buildings without either taking a scratch. Reign hitting Kara in the head with that thing should have shattered it to pieces.
