Quiet, it felt too quiet. Even for the city, it was what could only be described as deathly still. Still, there was nothing setting off alarms on Barry's phone, no paging to intercept a metahuman with an agenda; just a heavy fog, low and encompassing the buildings, so thick it turned the lights and traffics signals into soft glowing balls, vapor too dense to cut through.

"Do you know what time it is?" The low purr behind him was nearly made him jump out of his skin. The thief moved quietly on a good day, let alone on a rooftop surrounded by fog, the liminal space eery and unsettling.

"N-no?" Barry rubbed the back of his neck sheepishly, attempting to recompose himself without making a big deal about being snuck up on. Maybe it hadn't been on purpose, but knowing Len, it certainly hadn't been something he had tried to avoid either. The man got an unholy amount of pleasure watching people start when he showed up behind them, or next to them, his skilled movements and quiet presence having done nothing to give himself away.

"I know it's late? I, uh, came up here to think. You know, enjoy the quiet. Except, it's not really relaxing. Feels like things will come out and get you," he said, giving Len a pointed smile as he tilted his head at him.

Len nodded, smirking as he moved past Barry to the edge of the roof, looking out over into the sea of fog below. You couldn't even see the sidewalk, just presume how far away it was based on the memory. "Witching hour. It's three am. The witching hour, if you want to believe the notion that right now is when...things are most active. Ghosts, demons, witches, all so close you can feel them."

Barry laughed, moving next to him so he could lean forward onto the ledge with his forearms, head nodding as he looked down at his hands, finger distractedly toying with the costume concealing ring on his finger as he did. He leaned to the side as to be able to look up at Len, eyebrow raised as he regarded his partner with a dubious look.

"So it, uh, has nothing to do with the fog? Liminal space perception? The lack of echoing being unsettling to the brain?"

"No, no, entirely ghosts and demons. Demons do exist, Scarlet. Or did you forget?" He cocked an eyebrow at him as he settled onto the one elbow to get down on Barry's level. On the one hand, they both knew that was true, after all, Constantine and Sara were proof of that. On the other, the look on Len's face seemed to give the impression he was fucking with Barry, the knowing expression almost too serene. He looked like a smug cat, enjoying the slightest little toying, just curious to see if it would have any effect, not really looking for anything more than a result either way.

Barry tilted his head back and forth in concession as he tried to find a way to argue the point, while not admitting to a 'witching hour'. "I think you're giving a lot of credit to some fog and being up too late," he chuckled quietly, shaking his head finally.

"Maybe. Maybe not. But if you end up feeling this way again at this hour, and there isn't fog, well, you know where to find me to admit I told you so," Len said with an unaffected shrug, but his smirk had grown. "But perhaps, what is more active than the supernatural at this hour, is a scarlet ghost. Phases through walls, vibrating voice, followed by yellow lightning? Very creepy...You should watch out."

The only response Len received with a groan and eye roll before Barry nodded, straightening up and sitting on the ledge with poorly concealed amusement. "And you've uh, seen this ghost?"

Len nodded, looking away into the fog once more before finally speaking, voice holding even more than its usual quiet gravitas. "That I have. In fact, I haven't been able to shake it. I'm still haunted by it." He cut his eyes back to Barry and offered a tiny, more genuine smile. "And I think...he's very close by."
