Continuity mistake: An exterior view of the window in the building across the street that the Virtuoso plans on shooting from shows it is comprised of three square panes stacked vertically. When the Virtuoso is inside behind the window, it is one large vertical pane. (00:10:27)
Other mistake: The waitress said she got to Rosie's Cafe early and had to kill Rosie and the cook. She shot them and threw them down the basement steps, plus mopped up the blood before the loner arrived. The Virtuoso did not get there as early as he wanted to, but it was still about before 5:00 PM. He had briefly stopped along the road to ask the girl if she wanted a ride, and the waitress passed him at this point. The small amount of time the waitress was ahead wouldn't be enough time to kill and clean up. (01:35:30)
Character mistake: Still, not knowing who "White Rivers" is, the Virtuoso returns to Rosie's Cafe and continues to accept the Waitress' "passes." The Waitress was flirting (a mild term) with the Virtuoso from the time he first entered Rosie's. In addition to not abiding by his "do not get distracted" rule, he fails to even consider the possibility the Waitress was "White Rivers." Allegedly filling in for Rosie at the time given for the hit, plus her persistence in pursuing him, should have been a big red flag. (00:51:54)
Continuity mistake: When the Virtuoso goes into the kitchen at Rosie's Cafe, he sees three knives - two almost side-by-side with a third one between but below the two. When the Virtuoso goes to pick up a knife, there are now three knives side-by-side with a fourth one below the middle knife. (00:53:16)
