Many years before:
"She's beautiful."
"I know."
"I'm sorry. About Kira."
"No. It's not your fault, it's mine."
"Stop blaming yourself. Your daughter is alive!"
"And for what? So she can die too? Like Kira? No! That's not going to happen. I won't let it."
"I know you won't let it happen to her. To Isla. But you've got to let up a little, Padfoot."
"Fine. You want me to be happy? Fine. 'Yay! Sunshine and rainbows and unicorns! Oh wait…my wife is dead.' James, this changes everything."
"Not everything. You still have her, and she's going to be safe. With you. Sirius, you'll be an excellent father."
"I'm not ready, not at all. There's no way I can do this alone."
"You're not alone. You've got me, Lily, Moony, Wormtail, Dumbledore. So many people."
"It feels like I'm alone."
"It always does."
"You don't know that. Your wife hasn't died. You have a perfect little life. If…Voldemort wasn't at large, you'd be happy. Except for maybe me. I'm the Bludger to your Chaser."
"You aren't holding me back! Do you think that? Maybe you're just assuming that you're that important. Maybe you're just a speck of dust in my life, compared to my wife, and my coming child."
"Okay. You want to do it that way? Let's do it that way. Ridicule me. Make me even more sorry that I even tried to kill Snivelus. More than once, James, more than once."
"You know that he's on our side."
"Dumbledore thinks so. I don't. Believe me, James, one day he's going to turn on us, and we're going to be sorry we even looked at him as a member of the Order of the Phoenx."
"Padfoot, please."
"I'm out."
"You are still very much in."
"It's my decision."
"You're going to regret it."
"I won't. I'll be a normal wizard, a normal person. Finally."
