Brace yourselves, there is a lot to take in here...have fun!
Horizon. A person, a place, a thing? When it comes to Alias, Horizon could be anything. The true question is, how is Horizon related to SD-6? Sydney is kidnapped by DiSantis and put under hypnosis in order for her mother to find the location of Horizon. While under the power of several hallucinogenic drugs (not baby-harmful) Sydney is led back to her blood van days with Vaughn, as he rolls out the SD-6 map and shows Sydney the complexity that will be her life in the following years.
It is my impression that the purpose of the Alliance and the SD cells was to find and procure all of Rambaldi’s works. SD-6 was very successful, one because of Sydney Bristow and two, because Sydney Bristow and Arvin Sloane (as Nadia’s father) both play a part in Rambaldi’s grand plan. The only connection I can make is that Horizon is Rambaldi related and that is why its whereabouts was to be found on the Alliance map. Remember that there are 11 other SD cells that we know nothing about. The map was of all the SD cells and how they were allied with SD-6, who their suppliers were, who their leaders were and how far each cell might have reached into government agencies and such. Though it’s possible that Horizon could be linked to another SD cell, it makes the most sense that it has something to do with SD-6.
As discovered in the first half of season 5, P5 is made up of 12 cells, all of which have infiltrated 12 government agencies. Is it possible- related to KatyBird’s theory- that APO is one of those government agencies? Is it possible that the CIA has been penetrated by the anonymous group that killed Vaughn, kidnapped Sydney and is blackmailing Sloane?
Furthermore, we have to look at the characters that are also linked to P5. Sloane and Irina’s alliances have always been unknown. Their loyalties lie with themselves, their hidden agendas and to protect their children- we can hardly make any assumptions or theories in regards to their involvement, as it is likely to surprise us. What I do want to know is- did both Irina and Sloane know that their affair would produce the Passenger? Was Irina aware that her children are part of the prophecy when they were born? I suppose another question would be- has Irina seen Mt. Sabacio?
Also, it seems rather odd to me that Sloane would enter into a 30 year obsession with Rambaldi only to discover years later that he plays some part in it. His explanation is this: He and Emily lost a daughter. At the time he was studying Rambaldi manuscripts and in the writing he found comfort and hope. He then went on to research and explore Rambaldi’s work. It was my understanding that Jack and Sloane went rogue from the CIA, and Sloane entered into contract with the Alliance, to lead SD-6. Sloane recruited Jack, who would play double-agent and then later recruited Sydney. Come to find that Sydney Bristow is the Chosen One depicted in Rambaldi’s word. Too convenient, too coincidental.
Moreover, if Irina’s BIG agenda is connected to Rambaldi as well (as she seems to be front and center, hence her name on the box) then why has she spent so many years away from her daughters, the Chosen One and the Passenger? Irina is wise in all things Rambaldi, that is why Elena needed her to assemble the large Mueller, Irina had to have known all along that any child she bore would be somehow associated with the 15th century prophet.
These are just a few thoughts to mull over this weekend. What do you think? What is Horizon? Do you think it is Rambaldi related? What connections can you make between Horizon and SD-6? What about Sloane and Irina? What do they know that we don’t?
