Abigale forgot about her recent change in appearance in light of the intruder. Instead she took her spot behind Jack like a woman of her upbringing would naturally do. In the back of her mind she reminded herself to snip at Ms. Kane for speaking about finding 'everything still intact' under her clothing. It wasn't proper to speak of a woman's body in front of a man, "Sir, it would be wise of you to leave immediately," she snapped at the man in the window. If Jack or Ms. Kane weren't going to do anything about it, then she'd use the closest book she could find and throw it at the intruder. It probably wouldn't do much, but she wasn't going to just stand there forever, "This is a private party and I doubt you're invited," Abigale had the thought that this might be a servant of whom ever it was they were tracking down. Possibly sent to pay them off or even kill them before the game ever got started.
