He'd never been afraid of the dark, but after so long in the pitch black he was eager to see light again, and colour. So when he slowly opened his eyes and the first colour he actually saw again was black, an initial feeling of disappointment settled over him for a brief moment. Though this was soon quashed as the rest of the picture came into focus. Bruce, not in his cowl and cape, but in warm, comfortable looking clothing. He was reading, seated in a slightly reclined chair, in a room which appeared to be part of the Fortress. Though Kal couldn't for the life of him think how they'd come to be there. In fact, there was a disturbing lack in his memory.
He could remember the virus, borne of the Kryptonite poisoning that had invaded his bloodstream; taking over his body, shutting down his systems and obliterating cells, burning him up from the inside. Vague snatches of speech surfaced. Bruce explaining their plan to save him (stasis). Dick excitedly telling him that Kid Flash had returned to them from the speed force. Tim, obviously upset, admitting that they'd lost Conner. Closing his eyes again, a frown creased his brow, he could have sworn he'd heard Conner after that, more recently, though if his cousin was dead, then he couldn't have.
Drawing his attention back to the present he took stock of his immediate surroundings, noting he was in some kind of pod. Not dissimilar to the ship he'd arrived in all those years ago, crossed with the stasis chambers the JLA had been developing (and no doubt perfected). taking this information, he turned his thoughts inward, running a self diagnosis to check how much or how little he had healed. He felt okay, no burning through his veins and he didn't feel weak or sick. There was no pain. Taking a breath, he opened his eyes for the second time and carefully raised his hand to tap the glass front of the chamber which held him.
The soft noise may as well have been a firecracker going off, the way his friend reacted.
"May I come out now, Bruce?" Kal's voice sounded brittle from lack of use, the words hushed, no louder than a whisper. But that didn't matter, he knew Bruce had heard and he offered his friend a smile, trying to reassure and soothe each of the myriad of emotions crossing the elder man's face.
