People in an orgy drink wine. Orazio has wine. In a painting we see some blood coming out from a man's neck after a sword has apparently cut him there. Artemisia has some blood on her fingertips after losing her virginity to Tassi. Some may see Artemisia as having both for bucking the traditions of the time and for wanting to paint nude male models.
Artemisia lies about being a virgin during a court proceeding.
We learn that Tassi didn't tell Artemisia the entire truth about his marital status. We briefly see Artemisia's distorted vision during some sort of brief nervous attack. Seen in a painting at a man's throat where some blood is coming out. A few odd moments contain traditional scary movie music, but nothing frightening occurs during any of them. A few later scenes have some tense chords in them as well.
