Price Peterson of TV.com, in a positive review, praised the plot twist at the end of the episode. "The fact that [Troy] was a bad guy all along just proved to me that this show might just have some tricks up its sleeves." Rowan Kaiser of The A.V. Club also lauded the plot twist. While calling the episode "[the show's] next step forward," the reviewer also wrote that "the writers pulled the rug out from that perception in an impressive, not frustrating fashion." Matt Richenthal of TV Fanatic also remarked on Troy's negative side, but also commented positively on Keith's characterization. "We finally get to see a little bit more of Keith's emotional state this week, with the episode proving he was every bit as hurt as Veronica by his wife's sudden disappearance."
