Keep her lands

You tell her the truth. (Except of course for the part, you have taken in poisoning the king). She understands Henri must be giving out titles and lands to win support for his rule, so she is not angry with you. But you feel, you should keep those lands... You argue, she can't have them back, as she is already wanted dead by Henri! Those lands are safer in your possession for now... But still, you want to keep her at your side to protect her from future harm, that could come from Henri. She agrees, hugs you and you both keep travelling to your manor.
