I heard she was trying to stir the pot by telling Alex that Jessica called her a "panda"? Alex confronted Jessica then found out it was a lie. She then confronted Meghan, who couldn't take the backlash. But that's the way the game is played, right? You tell a few fibs, if you get caught, you apologize, save face, and move on. She was trying to play too hard, too fast. Got caught, and couldn't take the heat.
Having said that, on social media, she is hinting that it wasn't her choice. The plot thickens.
