I heard about the Sark trying to kiss Syd scene a while ago and from what I understand the scene was in an early script for Sucession but the scene was cut in the final script so unfortunately it was never filmed. Sorry to deliver the bad news! I do have some good news though. The way I found out about the scene was from a fanfic that is based on the AU that includes the cut scene. It is called Exchanges.

Ok, I hope that link works. Right now SD-1.net is down so I can't check to make sure that it does.
