[Cornelia knocks lightly on the door before she uses her key to open it. She just finished showering after her jog, so her hair is still wrapped in a towel, but she's fully dressed in pants and a short sleeved blazer. When she left that morning, she hadn't seen her sister stir, so she peeks in before seeing that the lights are on and that they have a guest.
Blinking, she lets the door swing open as she stares at the two of them for a moment. She can't help but feel the anxiousness tightening in her chest as she wonders what they might have been discussing. There are a lot of things that Cornelia chose not to tell Euphie, somewhat for her own protection, but mostly because Lelouch had made her keep silent until now. While there are things she still intends to keep to herself, she hopes that she can be more honest with her from now on. But what could they be talking about? She didn't even tell her sister that she had abandoned her titles to become rogue after her death.
Looking from one to the other, she tugs on the towel holding her damp hair in place and tosses it aside before shutting the door. Her expression doesn't betray her nervousness. Instead, she looks as indifferent as her tone seems to be.]
Guilford. You're looking quite comfortable. How long have you been here?
