It's lame no matter what the details or what happened to Claire are, and I can't believe they're setting up such a contrived excuse to create an obstacle between Kate and Jack, but looks like it's the case. BTW, the idea Jack and Kate would be a happy family if only he wasn't eaten inside by guilt or whatever issues he has, kills what what left of my respect for the writing of the romantic relationships in this show and any remaining attachment I had for my ship. This mess is just worse than a soap-opera.
