Actually, I believe there was a scene where Dr. Baker was giving Nicole some sort of post-grievance counselling of sorts, and they discussed how Nicole saw that her baby was dead. It was the same scene where Nicole admitted that she had "phantom" kicks in her abdomen, and where she also emotionally proclaimed, "My baby wasn't born dead, she was born sleeping!" then admitted shortly after that she was saying that merely as a coping mechanism (not meant literally).
Also, there were scenes where people remarked on the striking resemblance between Sydney and her Brady relatives. E.g., the scene where Lucas told Nicole that Sydney looked just like Allie did when she was that age. Then later that year when Sami was babysitting Sydney (before she found out Sydney was hers) and took Sydney to the Brady Pub, some lady assumed that Sydney was hers and then remarked that she thought this because the two of them looked so much alike.
Truthfully, I don't think the show producers are going to make Sydney end up being Nicole's. Unfortunately, it seems that every TV drama has their resident "kick around dog"...on One Tree Hill it's Brooke, and on Days it's Nicole. :mad: Not saying it's fair, just saying what it is. One of the characteristic traits of being in the role of "kick around dog" is being infertile, despite the overwhelming desperation to want to become a mother. They probably do this to exemplify just how pathetic the "kick around dog" really is, since (as I've read) infertility is one of the most emotionally devastating "disabilities" for an average woman to face. Furthermore, although Days has allowed for some miracle pregnancies in the past (e.g., Chloe's), there's been a few characters that were ALWAYS left childless, despite their best efforts and money, such as Vivian Alamain. Vivian did something essentially similar to Nicole -- she stole another woman's baby in an attempt to retain a man who was more in love with the other woman -- and in the end, not only did she lose custody of Philip, but she never had another opportunity to have an offspring of her own. I don't recall Ivan or Gus or anyone suggesting they adopt or try IVF together.
