We already love Lauren Juaregui and totally dug her first audition. As for Sister C, this was our first time really listening to them. Are you on Britney's side? The judge called their harmonies "annoying," and our girl Demi said they were really unlikable. Good thing neither judge drew "Groups" as their mentoring set — both Sister C and Lauren (via new girl group LYLAS) made it into the Judges' House round.
