Police storyline. Pointless murder, whatever. At least the scene is mercifully brief.

Joan comes down into the kitchen where Helen is working at the table. Joan remarks, "That looks like a fun Saturday." Helen says she's grading stuff: "You want a ride over to Grace's?" Oh, please. Am I really supposed to believe Helen bought that story? Yeah, it's not suspicious at all that Joan's staying over at Grace's house on the very night she wanted to go to the concert. Whatever. I wish my parents had been this dimwitted. Anyway, Joan says it's such a nice day that she'll walk: "I mean, if I'm allowed to." Helen: "Look, I know it's difficult…" Joan: "Mom, it's…cool." Helen: "It's not." Joan says there's nothing to talk about: "Grace and I are going to pig out on nachos and watch Donnie Darko so she can try to explain it to me again. End of story. Anything else?" Helen tells her to have a nice time. Joan says she'll see her tomorrow. Helen sits there brooding. How can she be so clueless?
