In an earlier episode that took place (after Zack died and Hope wanted some time alone) while Hope Brady was on the island with Patrick Lockhart, she sent an e-mail to Bo which Chelsea intercepted and sent a reply saying Bo wanted a divorce. Hope told Patrick her marriage was over and threw her wedding ring into the ocean while they were talking on the beach. Now that Hope and Bo are back together, her ring is now back on her left ring finger. Wonder how she got her ring back from the ocean so quickly?
