Hey, I just watched those episodes recently! The thing that kills me about the smiley face scene is that Data discovers that time is not standing still. Data notes that it's a warp core breach, which occurs so rapidly that the expansion is noticeable to him despite extreme time dilation. That would mean that the warp fog would be 1000s of degrees, even at their time scale. Picard should have gotten 3rd degree burns on his hand
