Just as clarification, where would Sylvia and Austin start--in their apartment? Since the events in the lobby already happened at this point.

Well, you got two choices. 

They're in their apartment, hiding from the chaos outside their door.

Or they were part of the crowd of NPCs that got ushered up the stairs, and have now just grown faces and personalities of their own.

Your choice :)
