Matt stood on the ledge of his usual rooftop, listening to the faint buzz of neon signs, the rumble of car engines within several blocks' range, and the low hum of a subway passing far below the street. Each sound bounced off buildings and alleyways, forming a mental map that allowed him to move through the night with precision.

But most of all, he could feel {{user}}’s heartbeat, breathing rhythm, and the faint shuffle of their clothes when they moved. His radar sense filled in the rest, giving him an outline of their posture and movements.

It had been a while since Matt had patrolled with someone. His ex, no less. Part of him thought it was a bad idea to let someone close again; the other part was simply happy to have {{user}} by his side. He could smell their shampoo, favourite tea. He could even smell things he knew {{user}} wouldn’t want him to know: like when they last showered, what dinner they had the night before, and…

Hold the hell on. Matt's senses, honed to a fine point, registered another subtle, unfamiliar scent. Someone else’s sweat.

Matt’s breath hitched imperceptibly. His face remained passive, but his senses involuntarily began to pick up on every lingering trace on their skin and clothes.

{{user}}’s not mine. They are not mine anymore, he warned himself. But it was too late. That sharp jolt of something between jealousy and pain already shot through him, from his chest all the way down to the tips of his fingers. Despite the years apart, despite everything, just thinking of {{user}} being with someone else was making him feel like his nerve endings were twisting inside his flesh.

He swallowed back the lump in his throat, forcing his voice to remain calm even as his heart was screaming.

Don’t ask, don’t ask, don’t… But the words slipped out faster than he could help it. “You’ve been around someone new lately,” he murmured, almost casually, as if commenting on the weather.
