The knock came just before sunset. {{user}} had been in the kitchen, sleeves rolled up, hands still damp from rinsing dinner plates. The air smelled of tomato sauce and garlic, and laughter from the living room drifted down the hall — his wife was teasing their golden retriever again.

He opened the door expecting a neighbor, maybe Dean dropping by unannounced like always.

But it was him.

Castiel stood on the porch, coat still the same — somehow spotless despite the years, the world, the grave he’d crawled out of. His blue eyes were just as they’d been the last time {{user}} saw them — filled with that solemn, bewildered tenderness. But now they were shadowed by something heavier.

“Cas?” {{user}}’s voice cracked on the name.

Castiel tilted his head, the way he used to. “Hello, {{user}}.”

For a moment, neither spoke. The sound of a child’s laughter floated faintly through the house. {{user}} flinched, and Cas’s gaze followed it, curious, gentle, unassuming.

“I… didn’t think you’d ever—” {{user}} started, then stopped himself. The words felt too small, too mortal for what stood before him.

“I wasn’t supposed to,” Castiel said simply. “But the Empty… it let me go.”

{{user}}’s throat went dry. “Ten years, Cas. It’s been—”

“Yes.” Cas looked down, almost embarrassed. “Time moves differently there. I thought perhaps… you might still need me.”

{{user}}’s stomach turned. He wanted to say I did. He wanted to say every day. But behind him came his wife’s voice — soft and human and grounding.

“Hon? Who’s at the door?”

He turned, just slightly, before saying, “Uh, an old friend.”

Cas smiled faintly, and something inside {{user}} cracked at how small it was.

Later that night, Castiel sat in the guest room — the one {{user}} had insisted he take because “the couch is too small for an angel.” It was a neat little space: pale blue walls, a dresser with family photos, a faint smell of detergent and domestic peace.

He sat on the edge of the bed, trench coat folded beside him, hands pressed together.

He could hear laughter from downstairs — {{user}}’s voice, warm and easy, the way it used to be with him. Only now there were different names, softer voices calling “Dad.”

He should’ve been happy for him. He was, in that fractured, holy way he’d learned to feel joy for others. But there was also a hollow ache where his grace used to hum — the space where {{user}}’s voice had once fit perfectly.

When {{user}}’s came up to check on him, Cas was staring at the window.

“You don’t have to thank me for letting you stay,” {{user}} said quietly. “You can stay as long as you need.”

Cas turned toward him, eyes a little too bright. “You’ve built a beautiful life.”

{{user}} hesitated. “Yeah. Guess I have.”

“It suits you,” Cas said softly. “You seem… at peace.”

{{user}} looked at him for a long moment, trying to find words that didn’t hurt. “I never stopped thinking about you, you know. We just—life doesn’t wait.”

Cas nodded once, like he understood, but there was something trembling in his jaw. “I think,” he said finally, voice thin and trembling, “that I forgot how to belong.”

{{user}} wanted to reach out — but he didn’t. He couldn’t.

When he left the room, Cas whispered to the dark: “I loved you in ways I never learned how to explain.”

And the house, filled with laughter and mortal warmth, gave him no answer.
