Claire was blissfully ignorant that Sylar was here in LA. Because had she known, any steps taken outside would be cautionary beyond normal, and possibly not alone. But as she hadn't yet be informed, she left her room as if it were any other day; aside from the whole darkness factor.
Hoping to either be of some use to the chaos or to bump into Xander or John, Claire walked with her head in an almost constant swivel, eyes searching for anything out of the ordinary or a glimpse of one of her friends. Most people had wizened up, though, and took to staying indoors as often as possible. It was a good thing, in the end, for them. It was a bad thing, for her, because it revealed herself to the very cab Sylar and Elle were in. Not thinking to peep into a cab, or any car for that matter, she kept walking down the street in the opposite direction they were driving, determined look playing on her face.
