Continuity mistake: When season 1 left off, at the very end of the last episode, Tuco examines the blue meth seriously and says, "What is this shit? This is blue." At the start of season 2, the scene is repeated, only when Tuco sees the blue meth, he laughs and then says "What is this? It's blue." Even though its supposed to be the same scene, the dialogue is slightly different and Tuco's demeanor is completely different. (00:01:05)
