While it is unlikely to be them looking to make amends (if the nurse returned with the truth) they are likely looking for her to prevent another uprising. Even if the (for foolishly stupid reasons) do not like her, she is still has the blood of the royal family in her veins and could be used as a figure head by factions who do not agree with the new emperor. To their eyes she is most likely a security risk hence why they kept her trapped in the tower.
