Castle: Scoop on episode 6x20 "That '70s Show" from TVLine's Matt Webb Mitovich

Here's some scoop on Castle from this week's (Posted on 2/28/14) Matt's Inside Line column.

I‘m extremely excited about Castle‘s episode set in the 1970s! Does the case revolve in that particular decade (á la “The Blue Butterfly”) or are we actually going to see flashbacks of Kate and Rick‘s early years? –Martina
The answer is… neither! As Stana Katic explained to me the other day, “In order to get information from one of our characters, we have to pretend that we’re in that era — because he believes that he’s still in that era.” But does that mean groovy threads and ‘dos for all? “I don’t know how extreme they’re going to go,” Katic answered. “But they’ve been playing around with, like, different hair and stuff — for the guys, mostly.”
