En route to Lord Lannister's quarters...
Toria found Desmera while she was on her way to her father's quarters and immediately sent the woman to attend to her guest. She didn't clarify who he was for Desmera - the walls had ears, after all. All she said was that it was rather important to keep him comfortable, content, and staying there. Ser Geron could see to that as well, but Desmera had a certain way of simply not putting up with nonsense. Perhaps a little gentler at persuading people than Ser Geron, but no less forceful when she needed to be.
Toria moved quickly and quietly down the hall, finally reaching her father's room. She knocked.
"Father? It's me," she said outside the door. "Do you have a minute? It's important."
