SPOILER ALERT!
I have gotten the feeling from the magazines that Zack is going to die, but his liver will be donated to Claire (Belle and Phillip/Shawn's baby...didn't kate change the blood results after she found that it was shawn's baby???)
That will end up helping with the Shawn being her father (genetics, long explanation!).
Chelsea further pulling Hope and Bo apart (apparently, Chelsea asks Bo to not tell anyone. Hope goes to pick up Zach from the babysitter and finds him in the street. Chelsea has no idea who she hit.)
etc., etc., etc......
