Panic rises on the quarantined seventh floor as the hospital patients and visitors realize they're locked in and a colored gas drifting in has scary effects, from smoke-like irritation to hallucinations. Only John seems immune, by his assumption the result of Stefano's experiments on him. Lucas just gets sleepy, Sami mistakes Elvis for his hated father, E.J. ends up fainted, falling down the staircase. Stefano, who faked paralysis, is up and able to pay surprise visits to Marlena and Sami, demands she gives him more heirs like Gianni.
