Continuity mistake: When Tony shoots Manny after he finds out that he has been with Gina, she runs to hold his bloody body, in turn getting blood on her robe. A few scenes later, when Gina comes into Tony's office, wearing the same robe, it is perfectly clean and there is no sign of any blood. (02:27:50 - 02:30:00)
Suggested correction: Actually, blood is visible on her robe in the close up shots of her. A spot can be seen on the edge of her robe right at chest level.
Correct, but she gets blood all over both sleeves. That blood is gone. Other than the spot you mentioned, the robe is pretty much immaculate.
