YESSS. geir would know siobhan, who is a fellow royal -- she had a fling with kris when they were younger & she didn't take being discarded all-too-well, and despite herself, harbors a little bit of a grudge. she's since gotten married to the king of france & is known to be politically-minded & rather cheerful in private circles, but she's also super idealistic. i think geir and siobhan would have likely butted heads when they were younger, but as they've grown up, she's probably put that aside for the sake of propriety & politics.
