He returns the kiss gladly, feeling somewhat shaken after everything, but certainly much improved; certainly closer to what serves as normal for him, anyway. Lightly he cups Watson's face, tenderly brushing his fingers against his skin. He's not sure he'll ever stop appreciating how handsome Watson looks in different situations, different clothes, different contexts. This rumpled look here, with his shirt undone, is quite enjoyable.

"So have I," he admits softly, and he settles his head against Watson's shoulder, letting his eyes fall shut. "It feels like years since we've done this. It's like coming out of a cave after days..." He sighs, glad to have admitted that much, and he nudges his nose against Watson's neck.
