Blue is a decent servant. She knows how to properly portray herself and does a particularly nice housework. She’s also good company and vaguely reminds Gaius of an old someone from his youth, which makes everything easier for both sides.
Gaius might control his house fiercely, but Blue barely represents any trouble for him at all, being a pleasant servant to have around for chilling and pampering when he appropriated.
