His irritation may be a little uncalled for. Leaning in, he kisses Watson's nose, and then his mouth gently, his hand cradling the side of his neck.

"It hasn't even been twenty-four hours. We ought to stop being so hard on ourselves. It isn't so easy to come back from the dead and declare a marriage, all within the same day." He kisses Watson again, his moustache tickling his lip, and he's smiling as he draws away. Reaching in, he smooths his thumb over Watson's moustache, arranging it neatly.

"I have missed your moustache," he murmurs warmly, a smile to his voice.
