"I... I... I want to come with you," Remus pleaded. "I want to help."
Sirius eyed him. "That shouldn't make you shameful. What does my cousin think
about you joining this little band of misfits?"
"She's with her parents."
"That's not what I asked," Sirius growled. "What are you hiding?"
His shoulders sagged, and he looked down as he whispered, "She's pregnant."
"She's.. ." Sirius lowered his wand at the unexpected announcement.
He remembered the moment that Lily had told them that she was expecting. It had
been one of the happiest moments of all of their lives, an announcement that helped push
them past a great deal of grief and sorrow.
Yet this moment was tense, and Remus looked so... guilty.
Sirius wanted to celebrate with his friend, congratulate him, but he promptly figured
out why the werewolf was in no celebratory mood. Eyes wide, he slapped Remus hard over
the head. "You dickhead!"
"Ow! What the hell?"
"You're leaving her? You stupid fuck!" Sirius shot red sparks out of his wand at the
floor, nearly setting Remus's cloak on fire.
"She'll be safer without me!" Remus yelled back. "I can do better being with you,
helping Harry! It's what James would've wanted―"
Suddenly, Sirius's wand shot back up as his blood boiled beneath his skin. The look
on Remus's face said that he knew exactly how poorly his words had been chosen.
"You want to tell me again what you think James would've wanted? You are not
Harry's godfather. I am. I am here to protect him, not you. I don't have a family. You do.
Now get your arse out of this house and go home to them. That's what James would have
wanted!"
"Don't you see what I've done?!" Remus's normally pale face briefly reddened in
anger. "I've made her an outcast! Bellatrix tried killing her because of me! And now she's...
And now my child... What if it's... What've I done?!"
"You still think that you're going to pass it onto your kid?" Sirius asked him
incredulously, desperately wanting to hit him again. "How thick are you? You've been told
for years that can't happen!"
Remus shook his head. "You don't know that."
