Harry is the worst sort of dim bulb, because it comes with a giant dollop of arrogance. So its no surprise if he has a complete lack of self-awareness that there might be consequences to his awful behaviour. KC does the right thing by swerving him.
The silly sod has aired his dirty laundry such as it is, not much apart from his brother shouted at him which from his behaviour in the last few years has probably been deserved for decades! He's sold his soul for money he didn't need and a shot at shallow celebrity (which the talentless duo are failing spectacularly at). So far its all a massive own goal, he comes off as a whining baby. The guy is nearly 40!
If this was my family nobody would give him the time of day either, we'd ignore him and let him exhaust himself till he was out of bullets. Then keep on ignoring indefinitely. Take his calls or meet with him - not a chance. Which is what the RF appear to be doing.
