Some TV scenes will always have a special place in our hearts for reasons even we can’t explain. They’re the ones we watch over and over until we’re pretty sure our computers or DVRs (or VHS tapes of episodes back in the day) are going to break from being rewound to the same place 100 times in a row. They’re the ones that we think of first when we hear the name of a TV show years after its series finale and remember the times when we were obsessed with that show. They’re the scenes that make us cry because they remind us of just how much we can love a show, a character, or a relationship.

When I think of the years I spent adoring (aka obsessing over) Alias, one of the first scenes I think about is from Season Three’s “Prelude,” when Vaughn helps Sydney escape to Rome and tells her, “even though everything’s changed, some thing don’t.” My 15-year-old self probably watched this scene 50 times within the first week after it aired, and I cried every time.

For those of us who were emotionally invested in Sydney and Vaughn’s relationship, the beginning of Alias’s third season was a rough time. We had to deal with Sydney’s two-year disappearance, Vaughn’s marriage, and the constant presence of his too-perfect wife, Lauren. By the time “Prelude” aired, things were looking pretty hopeless for Sydney and Vaughn “shippers” like myself.

But then this scene happened, and suddenly it was like we could see a light at the end of the tunnel. Some things hadn’t changed, and the biggest one of those things was Vaughn’s willingness to do anything to protect Sydney. When Michael Vartan delivers the line, “I’m not going to lose you twice,” you can feel Vaughn’s guilt over losing Sydney the first time as well as the conviction and love that I’d hoped was still in his heart. Vartan is so good in this scene. Vaughn’s inner conflict feels so real, and I love that—for a brief moment—the conflict goes away and all that’s left is love for the one woman he’d do anything for.

And how could he keep from doing anything for Sydney when she’s as heartbreakingly vulnerable as she is in this scene? When she tells Vaughn that her life is a disaster, I tear up every time. And her reactions to Vaughn throughout this scene are so genuine and beautiful. Her tears feel earned because we’ve been through so much with this couple, and we know how much it means to Sydney to hear the man she’ll always love tell her that he still has her back the way he did so long ago.

Hope is such a beautiful emotion to feel, and that’s what this scene is all about. When I first watched Sydney and Vaughn hold each other like they did so many times before, I felt so much hope. And when I watched Vaughn lean in to Sydney—his desire gorgeously written all over his face—I felt his hope, the hope of a man who wished for one second that he could go back in time to a moment when he could kiss her. And even after Sydney pulled away—her adorable smile trying to shine through her tears—I still felt hope. If they could have this moment, then maybe they could find their way back to each other.

This isn’t the best Alias scene ever. It’s not even the best Sydney/Vaughn scene. But it’s the one that holds the most precious spot in my heart because it gave me hope as a viewer at a time when I was looking for something positive from a relationship that used to make me so happy. Hope is a powerful thing, and that’s what this scene is all about.

As I keep posting these moments, you will notice that many of them will fall into a category I like to call “Actors Who Make Me Cry Whenever They Cry.” At the top of that list is Jennifer Garner. I watched Alias for five years, and whenever that woman let the tears fall, I found myself crying right along with her.

While Garner has some incredibly emotional scenes in the Alias pilot, the first scene to make me an emotional wreck came a few episodes later in “A Broken Heart.” With Sarah McLachlan’s heartbreakingly beautiful “Angel” (before it became overplayed) working its magic in the background, Garner allows us to see deep into the aching soul of Sydney Bristow, a woman pushed to her breaking point from bearing the weight of too many secrets, too many betrayals, too many lies, and too many needless deaths.

This scene proves to me that there’s never been a better crier on television than Garner. She’s not afraid to look vulnerable, to let her nose run and her mascara streak her cheeks and her shaking hands mess up her hair. And in doing so, she allows us to connect with Sydney, to see her as a real woman with vulnerabilities and a heart that’s perhaps too big for the work she’s been called to do. When she says, “He was lied to, and now he’s dead,” with such genuine devastation in her voice, I get choked up every time.

What I love about this scene is the way Garner makes Sydney—one of the strongest female characters to ever grace television screens—seem so small and so normal. She’s not a robot, and that’s what makes her such a beautiful character. Alias would never have worked as a show if Garner couldn’t make you feel the humanity at the heart of this character.

The range of emotions in this scene is so vast. It begins with sadness and anger that Jack would abandon Sydney again (though it’s really so much more complicated than that). Then it becomes a scene about loss—both for Sydney’s friend and for her sense of self. Garner sells her identity crisis so painfully well that I always laugh and cry along with her when she throws her beeper into the ocean—one act of defiance for a woman who feels as if she’s losing her ability to stand on her own two feet.

But when she can’t stand on her feet, this scene introduces the one person she could lean on, her greatest source of strength—Vaughn. I love the total sincerity in Michael Vartan’s delivery of “I’ve seen who you are.” Vaughn never wants Sydney to lose that humanity that makes everyone—including the audience—fall in love with her. And when the darkness threatens to overwhelm her, it’s wonderful to see that she finally has someone who can be her anchor, her guiding light, and her guardian angel, helping her find her best self because he believes in and loves her for exactly who she is—the only honest relationship she has at this point.

When Sydney grabs Vaughn’s hand and neither pulls away (despite the fact that they could be killed just for being seen together), I can’t help but cry because it’s the beginning of such a beautiful relationship. Sydney may carry the weight of the world on her shoulders, but Vaughn is the one person she can go to who will help her carry that weight. She may be incredibly strong—and he may be drawn to that strength—but in Vaughn she’s found the one person she can let her guard down with. Everyone needs a hand to hold when they’re at their lowest, and it’s a very emotional thing to see a character as beautiful as Sydney Bristow discover that she has that in her life for the first time.
