Not surprised, no, but there's something deeply bittersweet about how he feels seeing him. Bruce knows he's being obvious in his sudden unease, but he doesn't want to risk being too subtle-- he doesn't want to tell Clark what's going on, either.

Outside, Ace woofs at the figure floating in the sky, but it's just as Bruce is opening the window and the dog settles when he pokes his head out. He steps back to let Clark in, quiet; he's wearing a soft t-shirt and pajama pants, and the apartment smells like Chinese food. Equipped for a night in brooding.
