Arthur is doing as Faolan wishes, getting the lay of the land so to speak, trying to gather as much information as possible without ruffling any feathers. He's very cautious, keeping quiet and not making much contact with anyone but clanmates for the time being, but when he sees Natasha he can't really help himself. He observes her helping out some of the others first, and he wonders what capacity Redbright has her working in, but he's sure that's information he can glean just by talking to her.

So he approaches her with a smooth "excuse me" like he's about to ask for a goddamn campus tour.
