Well, I'm one of the unlucky people that don't have TIVO so I'm not able to watch frame by frame. But it's these things, like the pics in the black smoke, that make the show so cool.
Wow, I didn't even realize that there was anything in the smoke. Maybe it's my bad eyes or my TV but that's interesting. I thought last night's episode was very good! I also liked Eco's back story.
