There's a justifiably dubious note to Martin's echo, but he still curls an arm around him and presses a kiss to John's hair, which is a victory as far as John is concerned. He shuts his eyes, humming in quiet acknowledgment when Martin runs his hand along his arm, and thinks that he's successfully dozed off in less comfortable positions than this.

And then Martin tenses beneath him. It's slight, but impossible to miss with John draped around him as he is, and John lifts his head just in time to catch the pedestrian struggling onward and out of sight. Presumably after looking through the window at them.

His suspicions are confirmed by Martin's blush and the bracing pat he gives him, and John has to bite back a grin. "Oh, dear. Were we spotted?" He lets his head drop back onto Martin's shoulder, apparently unconcerned, though a part of him can't help but wonder just what he missed — and, as often happens, the suggestion of a question is enough to earn him an answer. "For what it's worth, he nearly fell on the ice before he could form any opinions about us, which interrupted his train of thought entirely. Now he's just thinking about how he should've gone shopping earlier in the day."
