Castle: Scoop on episode 6x20 "That '70s Show" from TVGuide's Natalie Abrams

I loved the "Blue Butterfly" episode of Castle. How will the show handle the '70s? — Kristen
While the gang will again be delightfully costumed, "That '70s Show" is more grounded in reality. In fact, Castle, Beckett & Co. only dress up in disco-era garb to pry the truth from a witness who still believes it's 1978. Unfortunately for Beckett, the witness shares Archie Bunker's views on women, which forces Castle to take the lead on the case — and in turning back the clock on the 12th Precinct. (Just wait until you see Esposito's reaction to Lanie's Foxy Brown get-up!)
