Everything about this exchange triggers Viola's instinct to play possum. Part of her wants to stand and chase after Felicity but she's so stiff with tension that she might as well be in the early stages of rigor mortis and she can't seem to convince her legs to move. It takes her a moment to register that Harrison is offering her his cigarette again and she accepts it cautiously. She feels oddly like she's gloating as she inhales, passing it back quickly.
Harrison & Viola... & Felicity
