“Brittany and Santana cover “I Wanna Dance With Somebody (Who Loves Me),” a tribute that takes a page directly from Houston’s 1985 video (for “How Will I Know”) in their second duet this season (behind Beyonce’s “Run the World (Girls)”). It’s one of the season’s most infectious performances and begs the question: Why haven’t we seen more of their home life? Scene stealer: Brittany for this gem: “Quinn, you’re still dancing in my dreams — and you can fly and breathe fire.” The only thing missing was a real kiss for this dynamic duo.” — x
