ok let me start off by saying this, I absolutly hate hate hate ABC and I hate when they do this to us. Dammit we get yet another cliffhanger and now we have to wait 2 weeks as if 1 week wasnt bad enough already now i have to wait two weeks.

Jack- boy oh boy where do i start with Jack. I dont at all blame him for the way he went about trying to protect His girl. Look at his point of view he spent almost all of Syd's teenage and adult years estranged from her and she hated his guts and believed he was responsible for Irina's death, so he missed out bascially on the important parts of Syd's life, and then when finally he began to get on better terms with his daughter she believed she killed lots of people and was k-dorrectorat after that passed and she began to have somewhat of a normal relationship with him, she found out he programed her as a spy and resented him and then tried to turn him in and when all of that passed and Syd and Jack were finally a real father and daughter bam! she is "dead" and he missed another two years of her life, I think now Jack is just trying to ensure that he doesnt lose a single second of his daughters life that is apparent to me when over and over he tells her that the invasive procedure is not a good idea and he wont let her do it. My two fave Syd/Jack moments remain from last season and the first.

This one where Syd and Jack were supposed to have dinner and Jack doesnt go and Syd pours her heart out to Vaughn, not only does this scene set up exactly how bad Syd/Jack relationship has been but also how badly she wants to have a real relationship with him and it also shows that Vaughn actually really cares about Syd, and the song (Sara M. "Angel) playing in the backround perfectly sums it out.

SYDNEY: (sobbing) I'm sorry to call you, I just didn't know who else to call. My father and I were supposed to have dinner tonight. The first time since I was a kid. I can't even remember the last time. (sobs) He just didn't show. He said he had work. He didn't have work. This isn't just about my dad. When I was in Morocco, the man who died... he was a friend of mine. He was a good man, who thought he was fighting for the right side, that he was working for the C.I.A.! He was lied to, and now he's dead. I had his blood on my hands!
VAUGHN: Sydney...
SYDNEY: I feel like I'm losing my mind! Like I don't even know who I am anymore, or what I'm doing, or why I'm doing it!
(Her pager suddenly beeps. Sydney grabs it, and throws it in the water below them. It splashes.)
VAUGHN: You just threw your beeper in the Pacific
SYDNEY: (laughs through tears) I know...
VAUGHN: Okay, listen to me. There's something you need to know. When you first walked into my office with that stupid Bozo hair, I thought you were crazy. I thought you might actually be a crazy person. But I watched you, and I read your statement, and I've seen... I've seen how you think, I've seen how you work, I've seen how you are in this job. In this job, you see darkness. You see the worst in people and though the jobs are different and the missions change, and the enemies have a thousand names, the one crucial thing, the one real responsibility you have is to not let your rage, and your resentment, and your disgust, darken you. When you're at your absolute lowest, at your most depressed, just remember that you can always... you know. You got my number.

and then this scene is my fave Syd/Jack scene ever they didnt interact in this scene but just the words show how much they long to have a real relatioship

Jack has a hearing with the senetor where he must give his reasons for his behavior
When asked if he turned himself in because he knew his daughter would do it he replied:

JACK: No, sir, that is not the case. (pause) Sydney Bristow, my daughter... has come to believe that when I look at her, I see the embodiment of all my flaws. And this afternoon when I learned that she may have been exposed to a life-threatening disease, I realized that she might die believing that. But nothing could be further from the truth.

(Fade to Sydney watching the hearing on the monitor in the joint task force building.)

JACK: When I look at her, when I look at the little girl who raised herself to become one of the most extraordinary human beings and one of the finest agents I've ever had the privilege of knowing, I see only the promise of my own redemption. Turning myself in was the only way I could think of to make that clear to her, to prove that despite... my limited abilities as a father, I love her more than I could ever say.

(Sydney watches and tears up as she has never been more proud of Jack)

And that scene between Syd and Vaughn last night boy that prved to me that Lauren is just a roadblock in the way of Sydney and Vaughn these two are meant to be together and they will be
