Harry has NEVER, NOT EVER, been anyone whom the Royal Family has “needed” AND he has NEVER “been there” for anyone of his own blood line family.
Yep - because every grieving husband needs a vicious sister in law, who has stabbed your wife in the back repeatedly and spread horrible rumors about her and made your little girl cry, back in the fold up close.
I don't think William needs his idiot brother for any comfort in a time of crisis. Harry has proven time and again that he has lousy judgment, sold out his family, and married trash. And said trash would not hesitate to try and capitalize on Catherine's condition to push herself into the limelight and some potential income.
Blood line?
I seriously doubt Chuck is his daddy.
The reason Harry was not told was because he and that cheesy wife of his would have sold the secret for money and attention.
Harry gave up his family when he married the grifter.
