Bruce's explanations marry with the information that Clark is reading, absorbed with supereyes and into superbrain. He arrives at that conclusion almost as Bruce says it, nodding along like he understands. He does.

Serious-reading-face softens, a breath of a laugh. Over the months of development, he's remembered what Bruce had said, about not needing to think about setting down a cup of coffee. He's reframed that goal into the idea of the sealed chamber, a place he could be, and train, and sure, reclaim that specific kind of intimacy with Bruce if they so chose.

He hadn't arrived at the conclusion that that place could be relatively anywhere.

Clark looks to him past his shoulder like he's about to say something clever or ask another question, but he says instead, "It's perfect." It's an idea still, sure, but a perfect one.
