Superboy wakes up in a prison.
In the cell, sitting across from him, there's a teen that looks like another offshoot clone of Clark.
He learns in bits and pieces that he's been captures by a shadow government organization hellbent on ridding the world of anyone "ecto-contaminated", or anyone who has ever been dead.
Since he'd died before, even though he came back, he set off their sensors.
He doesn't remember how he got caught, doesn't remember what he was doing prior, but the walls are made of a weird material that glows green and cancels out his powers. It also doesn't hurt him.
Diluted kryptonite? He'll have to steal some and give it to Tim.
According to the kid, they've been forcibly detained to "serve their sentence for illegal immigration from the Realm of the Dead to the Realm of the Living" by way of routinely allowing themselves to be subjected to medical procedures. They are always being watched, they aren't the only ones captive, that apparently his entire high school had been condemned to it as well as some literal ghosts, and if he struggles then they won't give him the mercy of sedation while they do their experiments.
And Kon can't use his power to escape, or free this kid, or free any of the other prisoners. It's the worst case scenario.
Thank fuck he's best friends with a paranoid Bat that might have more contingencies than the Big Bat Himself.
Kon activates the only subdermal tracker he'd allowed Tim to place under his skin, and settles down to wait.
A prison of this design, but more high tech and with less privacy. Apparently the idea behind it was that you couldn't see the guards, but they could see you, and the lights would move at random to make you think they were paying attention all the time.
So psychological torture on top of imprisonment.
