Continuity mistake: As Rhonda hands Shawn the glass of water in bed, he holds a cigarette pointing down. The close-up shot shows him receiving the glass of water and passing the cigarette to her with it pointing up. There was not enough time from shot to shot to re-orient the cigarette.
Factual error: When Tate is playing Scrabble with his grandparents, his grandfather tries to use "SIPI" as a word. Tate challenges that word. He looks it up in the dictionary to find out if it is not a word. He then says, "I see sip and sepia, but no sipi." To find sipi, he would have to look after sip, not before sip. Sepia comes before sip. He should have said, depending on which dictionary, "I see sip and sit, but no sipi."
