Yeah, you're right. Cause the spoilers say the sister is 5 years younger than Syd.ALiAs_AgEnT_423 said:Doesn't anyone find something serious wrong with this spoiler? Ok seriously did Sloane say he had an affair 9 months before Sydney was born? Do the math! There are better chances Sydney is Sloane and Irina's daughter and her "sister" is Jack and Irina's daughter. B/C Irina could have been pregnant right before her faked death.
