Owen waits impatiently in his truck, trying not to check his watch. He carefully watches the door to an apartment building. Soon, it opens, and Diego steps out, accompanied by his grandfather. Owen climbs out of the truck to greet them. Hector helps seven year old Diego get into the truck, as Owen neatly places his backpack in the back.

"Thank you for letting him spend the night," Hector says, as Diego closes the door. "I'm sorry that Father's Day was the only free weekend I had."

"It's okay," Owen says, waving before he gets back into the truck.

"Do you want to stop anywhere?" Owen asks Diego, as they drive away.

"No," Diego shakes his head. "I'm all right."

Owen quickly glances at his son. "What's wrong?"

Diego shrugs. "Nothing."

"Uh huh." They continue to drive, with Diego silently looking out the window. Owen keeps glancing at him. Diego is normally not a chatterbox, but he is particularly subdued right now.

Spotting a coffee shop, Owen pulls over and parks. "Let's get something to drink."

They sit down at a small table, Diego with a milkshake and Owen with coffee.

"What happened?" Owen finally asks.

Diego looks up at him quickly. "They're - not really my grandparents, are they?"

His father frowns. "Well - biologically they are. But your mother and I are your legal adopted family."

Diego nods. "It's - my grandmother Rita. She's talking again about taking me on a trip to South America. She says it's not fair that you won't let me go."

Owen sighs. "She might think it's safe but we don't." He privately thinks it will be a cold day in hell before his son leaves Seattle with his birth family.

"I don't like her," Diego blurts out. "She won't leave me alone when I visit. She doesn't like it when I want to read, she always wants to talk, talk, talk, and show me pictures of people I don't know. Grandma Hunt is much nicer."

Owen smiles softly. "Grandmother Rita wants you to know where you come from. It's hard for a parent to lose a child, I imagine she misses your birth mother very much."

"And she says lots of things that I don't like, about you and Mom," Diego continues, displaying a rare temper. "She says my clothes cost too much, you guys spoil me, you shouldn't let me read so much, you should let me spend more time with them. Do I have to visit them?"

Owen watches his son carefully, as he ponders his words. "You - don't have to visit them. There's no formal agreement, because legally, we have custody. Your grandfather was the one who asked, quite nicely, if it were possible to spend some time with you and get to know you. We agreed to it because we wanted you to know where you came from, and we didn't think it would harm you."

"Grandfather is nice," Diego says. "So are my aunts and cousins. But I don't want to have any more overnight visits. I hate staying there."

"Okay." Owen exhales. "We won't send you there overnight again. I'm sorry that you haven't been enjoying them. Thank you for telling me that."

Diego nods.

Owen continues. "Do you still want to see your grandfather? Maybe just him for a while?"

"I guess." Diego drinks through his straw. "I think I might want to go to South America some day. Grandfather told me about the reptiles they have where he came from. But I want to go when I'm older, after veterinary school."

"What happened to being an astronaut?" Owen grins.

Diego sighs. "They don't have animals in space, Dad."

"Not yet. You could be the first veterinarian in space."

Diego laughs, flashing one of his brilliant smiles. Then his face falls.

"What?" Owen asks.

"Grandmother Rita said I can't be a vet because I'm HIV+," the boy says quietly.

"You'll find a way to make it work," Owen assures him. "You're very careful. And you're very good at taking your medicine."

"Uh huh."

"You'll make it work," Owen repeats. "Look - we were told you might not live to see your first birthday. We were told that you'd never be able to take part in any sports because you were born with a heart condition. You keep proving people wrong. You can make it work."

Diego nods solemnly and pats his chest. "Mom gave me a good heart. I'm glad I live with you and not there."

"Me too."
