Summary
This fic is a Jegulus rewrite that’s very heavily inspired by Before Us — ik the original is orphaned, but still gotta give credit where credit’s due.
Regulus ends up as James Potter’s college roommate, which is already a nightmare, and then he realizes James also comes with a baby. A literal baby.
Between late-night bottle disasters, Rosie falling asleep on him, and James accidentally being soft, Regulus starts getting attached in all the wrong ways.
Meanwhile, Mulciber seems charming until he isn’t, and Regulus finds himself stuck in something he keeps trying to convince himself is normal.
Slow burn, messy emotions, bad decisions, and Jegulus pretending they don’t care (until they really, really do). -

Summary
On the night Voldemort comes to Godric’s Hollow, Lily’s sacrifice saves Harry — but a mysterious young woman saves James. Years later, James Potter raises his son with the help of Sirius and Remus, grieving his wife yet haunted by the memory of the stranger who looked at him with heartbreaking familiarity. When Harry enters Hogwarts and James finally meets Hermione Granger, he realizes the truth: the girl who saved him is the same witch who now walks at his son’s side.
What begins as a struggle to reconcile grief, fate, and fatherhood becomes a battle against destiny itself. Across the years of war, James must confront Dumbledore’s secrets, Harry’s peril, and the growing pull toward the brilliant witch bound to him by time. As Hermione discovers the cost of stepping into the past and James learns to live beyond the shadow of loss, their entwined paths reveal a truth neither can deny: this was the path that was always meant to be.

Summary
He’s watching the entrance when it happens.
Because he knows. Somehow, he knows before it happens- before the hush spreads across the gilded room like spilled ink, before the whispers start like hexes barely restrained.
Then the doors open.
And Regulus Black walks in like he owns the entire Ministry. Like he never bled for either side. Like he never disappeared and came back from the shadows and smoke.
And on his arm, impossibly smug and sleek in black velvet, is Evan fucking Rosier.
James’s mouth goes dry.
Regulus is a vision- sharp cheekbones, tailored silk deep green robes, silver rings glittering like promises he’ll never keep. His hair’s lightly tousled, a few strands left to frame his aristocratic face in the kind of mess that takes effort to perfect.
But James isn’t looking at his outfit. He’s looking at the way Regulus clings to Evan. Fingertips just resting inside the crook of his elbow. Smiling, faintly, like the whole thing amuses him.
And worse- he keeps looking at James.
Or:
The one where James and Regulus play chase.

Summary
Fuck JKR
Regulus Black is tired. Tired enough that, while interviewing for his dream job he apparently told his interviewer all about his fiancé and child (that he doesn't have). Actually, "told" is the wrong term. "Zoned out and nodded along" is a more fair assessment, really. He was snapped into reality when he started asking more specific questions about his partner. Which, always the compulsive liar and star people-pleaser when he panics, Regulus tells him that the kid being his partner's from a previous relationship and oh, now he's screwed.
James Potter has been a single dad since his fiancée broke off their engagement and disappeared. It's been a year and his friends are trying to convince him to put himself back out there, to date, to meet people, to get laid ffs. James just isn't ready to move on. To get them off his back, he convinces his best friend to stage a bunch of Instagram posts where you can't see his face to try to pass him off as his new boyfriend. Suddenly, his friends want to meet this boy he calls his little star. Problem is, Sirius isn't willing to keep up the charade. Now he has to find someone who looks like Sirius and is also crazy enough to agree to fake date him.
