Transcript for Family Surprises Soldier During Live 'GMA' Interview
Now, we have a very special event right here on "gma." A family reunion for captain gerry garcia. Just back from afghanistan. It took all kinds of maneuvers to pull off this surprise. That's captain garcia. He thinks he's joining "gma" to give a holiday greeting to his fellow troops on still on the front lines. He has no idea he's about to see his wife and kids, right there, right next door with cam mathison for the first time in almost a year. Cam, how is everybody doing? We are beyond excited here. Come on, guys. We're going this way. But we're doing our best to keep it quiet, obviously, because captain garcia is literally, come on with me, right on the other side of this door right here. So, obviously, we don't want to give it away. We've been planning this far too long. But before we get to the big moment, the big reveal, let's take a look at the garcia family history. My husband's name is gerardo. I've been married to him for ten years. We met in the military. I caught his eye. And he caught my eye. The rest is history. He's a funny guy. We are always playing jokes on each other or the children. He calls me the fuzzy man. Is that santa? I have three kids. Mark is our oldest. He's 10. Ales, she's 6. And our baby is 3. Reporter: Her husband, captain gerardo garcia is on her fourth deployment in afghanistan, while andrea holds down the fort in california. You love your husband so much, you make sacrifices. Reporter: While gerardo serves his country, andrea is getting her nursing degree. I need to be a model for them, too. That's why it was important for me to go to school, to better myself, so they can see mommy can make a difference while their dad's gone. Reporter: But raising three kids, essentially as a single parent, can take a tremendous emotional toll. It's hard. They don't get to see their dad in the morning. To say, hi, how was your day? Or get their dad to make them pancakes they used to make on sundays. Things that normal parents do for their kids. Reporter: But now, christmas is coming. And that means captain gerardo garcia is coming home for the holidays. But with a special twist. He has no idea his family is coming to the base today. An incredible early christmas surprise. I'm so ready to be able to hug him and kiss him and love on him. And just be together. The togetherness is what I miss is most. Hi, daddy. Hi, dad. I miss you, daddy. We are all ready for it, too, right now. Cannot wait for this moment. So, you guys, can you open my mic to captain garcia, please? Hey, captain garcia. George stephanopoulos here. Can you hear me? Yes, I can hear you. I want to thank you for your service to this country. Four tours in afghanistan. That's a tremendous sacrifice i know you have made. And I know you're there now to send a holiday hoo ha to all of your troops in iraq and afghanistan. We'll do that in a second. Before you do that, can you just turn around for a second? Um -- I'm sorry -- can you just turn around? Turn around, you said? Yeah. Can you turn around before we do the greeting? Oh. Hi. What are you guys doing to me? Wow. Love you. Surprise. There is real surprise. Oh, that is such a happy moment. I'm cameron mathison for "good morning america." I'm the eyes and ears behind the scenes. We wanted to surprise you. I hear that you are normally the family's practical joker. How do you think andrea did? Did she surprise you? Yeah. I'm speechless. I don't even have anything to say because I'm uard here. You didn't want to turn around. Yeah. I know george in new york wants to check in with you, as well. Oh, we loved seeing that moment. You were so intent on following the directions so well. You almost missed the surprise right there. Andrea, I want to ask you. You had to cook up such an elaborate plan to pull off this surprise. How did you do it? I had a lot of posting on facebook. Elaborate posts on facebook. That's what I did to take off this plan. And luckily, you know, he trusts me so much, it was very believable. Not after today. And I love seeing the smile on your kids' faces right now. They're going to get their pancakes this weekend, captain garcia? Oh, yeah. Definitely. Like I said, I'm speechless. I'm kind of shocked, believe it or not. After all of the things we did in the last year, this is probably the most chaotic one. They wanted to get you back. We have a little bit of breaking news here, everybody. Al allian we show what your dad missed. The first tooth has fallen out. Look at that tooth gone. Look at that. And now, you're here for it.
