When I do a final edit of this in the larger story it's extracted from, I'll change from this:
Quote
"Mr. Darcy’s son, of whom he was so proud, stood slender and straight and awkward and calm, even though only seven, looking at him with those steady dark eyes, so like Lady Anne’s, in silence, as was his nature. Mr. Darcy smiled a small smile of love and pride, which his son returned. Hopefully Fitzwilliam understood that, though young George Wickham could make him laugh like no other, it was only his son who could make him almost weep."
to something like this, which expresses more closely what I meant to say:

(It's George who is six years old and Fitzwilliam who is seven, by the way)
