Should we assume that Juliet is being truthful? What if she knows the baby was conceived pre-island, yet she wants to be able to study the pregnancy. Is Sun more likely to allow Juliet to be more involved if she feels like she needs her to save her life? Is the fact the she gave Ben the same info mean it is true, or just keeping the upper hand by her being the only one who knows for certain? I am not sure I take these sonogram results as gospel at this point due to accuracy issues and the Juliet factor.
