The opening scene of Season 4, which appears to be a flash-forward of sorts, shows Heather on her phone in a Bermuda hotel room. We don't hear the person on the other end of the line, but Heather’s responses are of shock and she even forces the camera crew to leave her room. The last shot of her, before things revert back to “present day,” shows Heather telling the mysterious person on the phone, “How did we all fall for it? I don’t know who to trust anymore.”

According to some, the most logical person who called Heather is Jen Shah, her former RHOSLC co-star who is also serving a 6.5 year prison sentence for conspiracy to commit wire fraud. Jen is notably absent from Season 4, being that she is incarcerated for the foreseeable future. Heather was by Jen’s side for most of Season 3, while Jen traveled out of state for court and while she was on trial.

Later, however, Heather admitted to Us Weekly, things changed for her when Jen pled guilty. She told the outlet that her focus was “the victims and [Jen’s] family.” So if Heather cut ties with Jen upon her sentencing, it's possible that Heather remained in close contact with Jen’s husband and kids. And if that’s the case, then another option for who called Heather could be Jen’s husband, Sharrieff Shah.
