I would make some sense wouldnt? Irina is obsested with Rambadi but she is not the type that would help bring about the end of the world. I also believe she does love Syd and i also do believe Syd is the chosen one in the Profecy. it would make sense that she has kept Syd asleep away from sloane, because well i think Syd could bring about the end of the world with "the Telling" thing or whatever but its her choice and one she mite be made againest her will. So maybe, just maybe she has been out and for some reason Irina decided its time or maybe Syd escaped, i don't know. But i must raise a question, in the last ep, sloane siad it was ready, the telling that is, so one must assume he has used it, u know after 2 years And my side Theory, Time Travel, i don't know how are why but it has to do will the telling. it just seems to me its alittle for far fetched for Syd to be missing for 2 years and to skip 2 years in storyline. the whole face of the mission of the joint task force, even the world must be changed. i dont know All i can say is a quote from a recent Episode, "Truth Takes Time" One more thing, evil fracie crying over killing Will, hmmmm, and vaughn saying both fracie and will are alive 2 years later, WELL THEY BOTH LOOKED PRETTY DEAD, will in the bathtub and fracie with a gory shot to the head in 'Phase one". think about.
