"My personal life has nothing to do with your overstepping," Ashley fires back.

After the battle is stopped by Devon (Bryton James) and Simon (Michael E. Knight), however, Hilary will still refuse to let it go.

When Ashley wakes up, Hilary will confront her and use her new knowledge as blackmail, telling her that she won't make her status as a patient public if she voluntarily steps down from her position and names Hilary as her successor.
