Can we discuss Heather over the seasons?

Rewatching, and I’m seeing so much behavior from Heather that never gets addressed on the reunion.

For example:

• During Heathers breaking ground party, she told the person doing the bull to turn up the speed on Tamra. Tamra falls, hurts herself, and Heathers asks if they should sue.

• Heather and Shannon’s chair incident. Heather completely rewrote history, saying Shannon was screaming. That Shannon was scary angry.

• When Vicki’s mom died, Heather has to call Terri and starts crying?

• Heather leaves the sushi restaurant and cry hysterically on the phone with Terry that Kelly used the c*nt word?

• Every time anyone has an emotion, Heather says “do we need to call an ambulance? I think they’re having a psychotic break.”

What else? And why is she not being held accountable?
