Tiny pictures connected to the message board were really nothing as far as recognition, so Sarah didn't immediately attach the woman in the lobby to the name Angela Petrelli, but even if she had, her smile would have been no less friendly – but possibly slightly more chagrined at sounding out Darth Vader's theme with a plastic light saber in hand.
"I hope we're not disturbing you," she said after she had cleared her throat, even as her gaze swept the lobby for signs of either boy, either by sight or by sound. If they were together, there was no doubt that inevitably someone would reveal their location as they elbowed for better hiding position. Of course, the office door moving slightly on its hinges told her at least one wasn't in the lobby.
"On the fly addition – no outside help in hiding!" she called toward the office, perhaps quite accurately heading off any attempts to engage superpower-fueled help before shooting the woman another smile of apology.
