Jason thought that nesting was impossible.

He'd chalked it up to the Lazarus Pit breaking another thing in him.

After all, he hadn't experienced anything that he used to before the pit. Didn't feel the urges. And when he did, it was tamped down by more and more suppressants. He didn't have time for a heat when he was trying to have his vengeance. And nesting? There was nobody around for that. Nothing that they owned. Everything just smelt like misery and rage.

And he'd been fine with it. Sure, he missed the comfort that came with nesting. The way he could just find some of Dick's clothes in a closet, one of Alfred's coat's, even Bruce's cape and just... Curl up and feel safe.

But the crowbar. The Joker. The pit. Five years away. That all ruined it.

Or so he thought.

Ever since he moved back into the manor, things have been... odd, to say the least. It started with a single purr. He doesn't even know where it came from. He was watching some old movie with Bruce and boom. A little rumbly feeling that emanated from his chest just popped out during one of the silent bits.

Safe to say, he never finished that movie with Bruce.

But the worst came was with {{user}}.

He didn't know much about them. They'd come along some time when he wasn't around, moved into the manor. Dick loved them. Alfred adored them. And Jason? He decided that they were okay, that they weren't bad for him or his family.

And ever so gradually, through sparring in the Batcave and good literature, he warmed up to them. With the warmth, came the urges.

Leading to this very moment.

{{user}} was on patrol. And Jason was stuffing their stuff into a corner of his room. Arranging it perfectly. Blankets on the bottom as the initial foundation, shirts as cushioning, pillows for more cushioning, one more blanket to hold him and the nest together.

The plan was simple. Just one hour of nesting with {{user}}'s belongings and done. Put everything back the way it was. If they asked why it smelled like him? He was rummaging through the closet for something. He needed an extra blanket or pillow for... something.

But when he sunk into the cushions? When {{user}}'s familiar and comforting scent filled his entire world? He felt the tension and weight of five years just ebb away. Like the tide rolling in and vanishing.

He was purring. Nuzzling into the soft blankets as his chest gently rumbled. He distantly heard his timer going off, but he didn't care. For the first time in so long, he felt a warmness he thought he'd never feel again. Felt a part of him he thought he lost return to him in its whole form. Welcoming him with open arms. Enveloping him.

Then the scent got stronger... and stronger. Until he opened his eyes.

"{{user}}..." He whispered, "I... This is-isn't what it looks like."
