Alias series finale question

[ASUADPi]

Okay....

The first episode (two parter), what do I remember (I have the second part via Itunes).

Marshall and Rachel were kidnapped by Sark. Carrie found out that Marshall was still in the CIA and demanded to help find him. Tom and Rachel almost kissed (or did, I can't remember). I don't remember what Vaugh, Syd or Sloane were doing at the time. There was a bomb put in the CIA building or someplace near it (underground). Tom went to difuse it but really wasn't able to, or something. Anyways, the bomb went off, killing Tom. Marshall and Rachel were found prior to this (because Tom and Rachel talk and he tells her that he would have asked her out on a date and she says that she would have said yes).
Syd is like in Antartica or something. She falls into a cave with ice and snow and passes out. Vaughn finds her and saves her (duh). They travel around. They find Sloane someplace, can't think where right now. Jack gets shot. He insists that Syd and Vaughn go after Irina. They leave. Now, Syd had shot Sloane and assumed that he was dead, but in reality the Rambaldi device gave him immortality. Well Jack goes into the cave with Sloane and tells him that he isn't going to hurt his daughter (Syd) anymore. And that he will keep him in the cave with him. Jack then detonates the bombs that are in his hands, thus killing himself and trapping Sloane in the cave. Now Sloane has been seeing Nadia (ghost) since he killed her. He sees her in the cave and she tells him that he has all the time in the world (hence the title of the eppy) and "leaves" him. Now Syd and Vaughn are another place. They find Irina and Sark. Sark and Vaughn fight, Sark escapes. Syd and Irina fight. Irina lands on a glass window, the pane cracks and she falls to her death. The satalite that they were trying to get to land on the planet passes by, no harm, no foul. Syd and vaughn hug.
Flash foward about 8 years. A little girl is playing on the beach. She calls "uncle dixon" and "daddy". Turns out it is Isabelle. Vaughn comes out of the beach house. Syd follows with a baby, who is named Jack (yes you can go, awwww). Dixon is there to ask Syd to help him out with finding Sark, she gives vaughn a hard time for letting him go. They take a walk on the beach and that is the end of the episode.

Obviously there are other things in the eppy but I think these were the important details. Questions feel free to ask!
