Okay so you may have guessed I am going with high risk pregnancy. I'm going to go with the trauma Kate suffered to her heart years back let's just say her heart and her lungs are in a weakened state for such things as childbirth and pregnancy. Oh and Kate has been warned previously, and some of that information but not all has been passed on to Castle... So Castle will not be happy. A baby he would be ecstatic in normal circumstances but not at the risk of losing Kate. Kate however knows he would have loved a baby and feels he would resent her. Not true of course!...Now Kate keeping it a secret...you know waiting those few more weeks...I wrote that not knowing where I was going...so I read up on abortions in Australia... . and it states it is illegal in NSW except when the mother's life is in danger...so that doesn't really apply with Kate's situation because they would do it regardless of weeks...so I guess she is just waiting and has a number of weeks in her head so that Castle or the doctors won't make her do that?
