E! caught up with Sean after the show, who admitted that he "did not perform my best," to put it lightly.
"I think you screwed up everything but the solo!" Peta joked.
Despite the iffy technique, Sean said Catherine loved the dance. "She thought it was incredible," he explained. "I think she saw the emotion coming out of me, so she knew it was genuine and sincere, and I knew it was a very special moment for the two of us, so that made it worth it right there."
He also said that his fiancee gives him 10s every week, judges be damned. Aww.
E! Also talked to D.L. Hughley about his best dance of the season so far, and Zendaya Coleman about being compared to Beyonce. For more from the cast, watch the interview here.
