Spoilers: Let's Talk Motive

[Ravenwhiteclaw]

Hello fellow Nancy Drew enthusiasts. I am trying to understand Charlotte's will. More specifically why did Charlotte change her will from leaving the family business and estate 100% to Clara to 100% to Harper. I know that early in the game Wade says that Harper disappeared for some time and that is why there is a tombstone with her name on it in the graveyard. However, making such a substantial change seems odd. Also, how did Clara know Charlotte made this change? Considering the lengths Charlotte went to to hide her will it would seem foolhardy for her to bluntly reveal this change to the person it negatively impacts. PLEASE HELP ME UNDERSTAND.

I just finished this game and I'm struggling to understand this too. What made Charlotte turn against Clara?
