[Aside from her usual session in the dojo, Saber had spent the majority of the day relatively nearby-- close enough to know just her master's location, but completely out of his sight and sense. Just in case an emergency arose. He'd made it clear the other day that her actual company wasn't needed or desired.
Just like Kiritsugu. She's tried to prevent that situation again, to be something Zelgadis could and should depend on. But realistically, she just needs him to sustain her long enough til a way out can be found. Anything more is unnecessary]
[Quietly opening the front door when she returns for the evening, she prepares for yet another quiet meal-- until she enters the main room to see something along the lines of a full course meal or more set up, and she has to pause in taking off her jacket from surprise. She gives her waiting master a look of complete puzzlement for a moment, before breaking the terms of silence for a necessary question]
Are we-- you hosting a dinner of some sort, Master?
