How awesome would it be if they did? I previously wrote in another post that the tension that would cause would be a great story line! I think they should have wild "hate sex". And if she ever had to bring him down, Syd would be so conflicted b/c she hates him but there is that whole physical attraction going on.
i'm totally an s/s shipper (also an s/v shipper but that's cuz i think it is likely to happen). i don't think jj will put them together because i don't think it could work very easily. even if syd was head over heels for him, he's the enemy. she's too devoted to her country for it. but it would be NICE!
