A few days ago a Q & A interview was done with Julie and she was told that there are a lot fans out there who are Team Rebecca and want her back together with Christopher. It's true and I am one of those fans.
Christopher and Elena will not last in my opnion. Many thought the marriage was going to be annulled but it can't. A divorce is the only option now that was confirmed last night. A divorce will take time especially with kids in the mix. Julie and Jesse have confirmed that theit two characters are now in a custody battle over their unborn twins. I doubt there will be a wedding or a divorce personally but we'll see.
Julie has said that there some tense scenes between bewteen Pamela Rebecca and Christopher but it will not always be that way nor will Rebecca alway be angry and out for revenge.
Jessie said in his interview (Q & A) when asked, that yes, Christopher is still emotionally vulernable to Pamela Rebecca because she is after the mother of his children.
