Somebody remind me about the woman who hung herself who's she

She's heinrey's sister-in-law, the former Queen but she got moved out of the palace bc of a power struggle

The b*tch that tried to seduce Heinrey using love potion and tried to spread some false rumor about her being his lover. She left the palace after her lies were exposed. Lastly, she is the daughter of the old guy that tried to give Navier that abortive food during the new year ceremony.
