When he next woke up, he was alone. Well, mostly. The other patrons in the Bat Burger weren't there with him, but he could tell that Jason was somewhere near-ish-by.
He didn't open his eyes, nor did his unneeded breathing change past his resting rate. By sound alone, he knew three of the walls were cement, as well as the floor and ceiling. The last one was either bullet-proof glass or metal bars. The smell in the cell hinted at the former rather than the latter.
It was storming outside, he could tell, proving that he wasn't underground. All of the buildings in Gotham, minus skyscrapers and warehouses, were made of brick, so he probably wasn't in Gotham Proper anymore.
A buzzer went off somewhere down the hall and Danny suddenly had a horrible inkling as to where he and Jason were being kept.
"Danny?" Jason whispered from the cell immediately next to his own. "You there?"
He made just the right amount of noise when moving to alert Jason before he spoke. "Right here. You have an idea of where we are?"
A beat. "Yeah," he said quietly, almost nervous, "You?"
He nodded. "Yeah."
"We've been out for about three hours, I think." Jason's voice was still as quiet as he could make it while having Danny still be able to hear him. "I didn't manage to hit my panic button before it was frozen over, but three hours should be long enough for Alfred to realize something's wrong. The others'll-"
"No!" Danny growled, "We're getting out of here without the others' help."
"How do you plan to do that?" His voice wasn't condescending like he was half expecting. It was steady, still quiet, and patient.
He was waiting for him to propose a plan, Danny realized. "They really didn't tell you a thing about me, did they?"
Jason hummed. "Well, Talia said that you were to be treated like a civilian-"
Danny scoffed, "Yeah, well, I was never a civilian in the first place. I may be younger than Damian-"
"I'm sorry," he spluttered, "'Younger'?"
Danny ignored him, "-but I have just as much, if not more, fighting experience than him. Not to mention the superpowers!"
"The one's you got from dying," Jason reminded himself, "Right. So, what's the plan, ghost boy?"
Danny blinked. "'Plan'?"
"You do have a plan, right?" A beat. "Right?"
"Just follow my lead."
"You don't have a fucking plan?!"
"I what universe would I have a plan for this exact scenario or any like it? Who do you think I am, Batman?!"
"Fair," Jason conceded, "How are we gonna get out of here? It's Arkham fucking Asylum!"
Danny raised his eyebrow, fully aware that Jason couldn't see him. "You don't have the layout of this place memorized? I thought you guys locked people up in here all the time?"
"We send them here. B keeps us far away from the island itself."
"Hm," Danny shrugged, "Skill issue."
"Excuse me?"
Danny stood and started looking around his cell. Like he clocked, the wall to the hall was modified glass with no obvious weak points. The floor, ceiling, and three walls were all smooth cement, painted with some kind of frost-like gloss that made them cold to the touch. There was a single cot with a thread-bare blanket and no pillow. A single LED light in the middle of the ceiling lit up the box, and there was a vent in the far corner, bolted to the wall with so many screws it was ridiculous, and too small for probably even Damian to fit through.
"Then vents on the inner-most cells don't lead directly outside," he said to himself, "But I can hear the river." Louder, he said to Jason, "We're in the outer-most cell-block."
"How the hell do you- You have the layout of this place memorized?"
"Yep."
"Why?"
And that was the question, wasn't it? "Just in case I ever needed to break out." Or in.
Jason huffed and began pacing his cell. "I'm not gonna ask. I wanna know, but I'm not gonna ask."
Danny shrugged. Fine with him.
Jason cam back to the corner of their shared wall and the glass panes. "How do you plan to get out of here? The vents are too small."
"Well, how do your Rogues normally get out?"
"Depends on who we're talkin' about. Some blow up a few walls, some have their goons already working here, others pay off the guards. Take your pick."
Danny thought for a moment. "Unfortunately, none of those will work for us, though blowing up a few walls sounds like a lot of fun."
"Yeah, until someone has to clean up the mess." He could hear the smile in his voice.
"You want to do this the easy way or the long way?"
"There's an easy way?"
Danny let his intangibility wash over him and stuck his head through their shared wall. "Ghost, remember?"
Jason laughed. "And the long way?"
"Find out what your two Rogues are planning, wait for the others to come to save the day, and then escape on our own anyway."
Jason raised his eyebrow. "Which do you wanna do?"
