"I want to be a RAB member and nothing else," he says. "When I grow up, I want to bring them to justice."

Such talk worries his father.

"My biggest fear is that he'll start to think, 'I will find the person who did this to me and I will do the same to him.' He will live in a world of revenge. "I don't want this. I don't want to be the father of a terrorist."

The pieces fit

John Gearhart is the director of pediatric urology at Johns Hopkins Children's Center in Baltimore, Maryland.

As one of the nation's preeminent urologists, he has treated hundreds of children born with birth defects or ambiguous genitalia.

If anyone could make Okkhoy whole again, he could.

So, CNN reaches out to him. And he agrees.

"You just can't imagine another human being doing this to another human being, frankly," he says. "And even though he is Bangladesh and I'm in Baltimore, to be able to change one child's life is why you go into pediatrics."

Gearhart then enlists the help of a few other colleagues, who -- like him -- volunteer to donate their time.

With a medical team ready, the rest of the pieces quickly fall into place.

Qatar Airways offers to fly in Okkhoy for free. Staffers at the Bangladesh office of International Organization for Migration prepare him for what to expect in the United States. And Kovach agrees to bear the rest of the family's expenses.

"They say angels live in heaven" an ecstatic Abed exclaims. "These compassionate souls are proof they live among us too."

A nagging question

It's late afternoon when father and son, accompanied by their court-appointed guardian Alena Khan, fly into Dulles International Airport. It'll take another hour in rush-hour Friday traffic to arrive at the townhouse near the Baltimore hospital where the family will live for the next month.

"You've been on our minds for about a year or so. So, I'm glad to meet you and I'm glad that you are here," Kovach says when Okkhoy arrives.

Real life sometimes does not live up to the movies.

There are no scenes of an indebted Okkhoy running up and bearhugging Kovach. He is delighted at the suitcase full of toys the businessman has brought for him, but he is tired and jetlagged to show it.

His father, too, is weary from the 17-hour flight -- and wary about these strangers' motivations.

The next day, as the Kovachs' take the family sightseeing, Abed decides to ask the question that has gnawed at him.

"I have only one question: Why are you doing this for us?" he asks in Bengali. "Because I love him," Kovach says through a translator. "I felt his grief, I felt his pain and I just wanted to do something. I mean, if it was me, I was hoping somebody else would do the same thing for me."

As he speaks, Abed quietly listens. Tears well in his eyes.

"Thank you, thank you," he says in broken English.

The two men hug.

"It's just what we do," Kovach says. "It's just what we do as human beings."
