While it's been the worst kept secret in daytime, Soap Opera Network can finally report that actress Molly Burnett is returning to NBC's "Days of our Lives" in the contract role of Melanie Jonas, a role in which she originated in 2008. Burnett, who left the soap in 2012 in order to pursue outside projects, returns to Salem as her character harbors a secret that even daddy Jonas (Shawn Christian) isn't aware of!
