Continuity mistake: Eric's men completely trash the clinic's lobby; in particular they tear down the "Accettazione" sign. However when they finally leave, the place is still completely messy but the sign can be seen in the background when the snitch is spared his life and gets up. (00:08:20 - 00:09:45)
Other mistake: At the end of the episode, the police inspector picks up a single .357 casing that Zenigata assumes, correctly, is the one from the shot fired by Jigen. He picks it up from behind the bench, but there are plenty more on the ground in that spot, which does not make sense considering he was the only one shooting from that position. (00:19:15)
Continuity mistake: When Zenigata walks away from the inspector, the Italian colleague is standing by the bench, which appears mangled by projectiles for roughly half its length, while it was damaged for a more extensive part before. (00:19:30)
Continuity mistake: When Nino collapses (camera positioned behind Jigen's head) you can see a blood streak on his right arm as well as the left arm. In the rest of the scene he has blood only on the left arm. Moreover, when Jigen picks him up the puddle of blood on the floor has a different shape compared to what we see when he leaves doctor Livia to her medical duties. (00:12:20)
