It was not in the cigarette. It was an ant crawling on his right thumb between the knuckle and the joint to his wrist. Please don't say anything in reply. I jumped ahead one episode in my viewing of the series. Don't need you giving me a spoiler please!!!
I saw the ant, but why would an ant scare him? It looked like there was some white object in the cigarette he was trying to roll. (I haven't watched the rest of the episode yet, I got stuck trying to figure that out.)
I think I need new glasses, maybe I should try a 1080p instead of 720p.
