It's one she will never forget.
While his family watched him deliver a pre-recorded message, Sgt. Robert Reyna, Ana's husband, popped out of the camera well along the third-base line to a thunderous applause and stunned looks from his family.
Robert wasn't due back from Korea until August, but he saw the earlier date on his military orders and decided he wanted to "make things interesting." He contacted the Astros, who customarily honor a member of the military during every home game in the fourth inning, and set up the surprise homecoming.
"I was shaking. I was so happy, just wanted to see them so bad," he said of his entrance. "I completely didn't hear anything around me."
Ana focused on the video initially, pointing out her husband's face to her 3-year-old son Andrew, whom she held in her arms.
"He was saying, 'Daddy, I saw you,'" Ana said.
Then, Andrew saw his father for the first time in 10 months.
Robert's father, Robert Reyna Sr., wiped tears from his eyes as his son held Andrew tight and embraced Ana.
"I've seen that before and I never, ever thought it would have happened to us," Reyna Sr. said. "Couldn't hold back the tears. We're just so surprised and overwhelmed."
Still visibly shaken after the surprise, the Reyna family gathered in a private dining room in the Diamond Club, where Reyna's mother, Yvonne, played the scene over and over in her head.
"When I saw his face up on the screen I got a bit emotional, but when they told us to turn around, and when I did I saw someone in uniform," Yvonne said. "It's going to take a while to come back down."
In addition to his work in Korea, Reyna served one tour in Iraq during Operation New Dawn from 2011-12. He's worked in South Korea since 2014, training with the Republic of Korea Army. He has four years of active duty in the U.S. Army.
