Still with the daddy's d1ck thing? Such a weird couple. And that they are still together after all this is still weirder.
It's not that weird. This is my assumption what happened.
1. Mason cheated on her or fooling around.
2. She became paranoid, controlling.
3. They fight a lot after that.
4. Physically hitting each other.
5. One night when they had a big fight Harriot took all the photos just in case.
6. They got back together again. Maintain the relationship.
7. They fight again and Mason threatened to leave her.
8. She said she will upload evidence saying Mason is abusive and she will destroy his career.
9. The reaction was global, it goes way out of hand.
10. She took off the evidence, but too late.
11. Parents got involved.
12. And then what publicly happened, happened.
It's the most logical explanation.
