Artie was supposed to be staying with Larkin, but she suddenly received a familiarity quest asking her to help Saritsa finalize the wedding details. That was why she had to excuse herself and just leave Larkin to think by himself. He was more productive that way after all.
She was just thinking of things regarding the wedding based on the arrangements that Miel had done for his father's second marriage. Then again, a royal wedding should be more complicated. As she was not the main planner, she was hoping that she only needed to give a nice date or to speak with some people whose presences were necessary. She also thought of inviting Alfora since the wedding should be held in Talcum instead.
