I bet Vronsky and Wickham would have been friends.
They’re both ladies’ men.
They’ve both gone after high-society women (Anna and Georgianna—hey, their names are even similar).
They’re both soldiers.
They both end up in not the happiest of situations (married to Lydia and trying to get himself killed in the Servian war, respectively).
I can just picture them both sitting in a bar, good-naturedly arguing over whose woman is better while simultaneously complaining about said woman and swapping war stories. Two peas in a pod.
What other literary characters do you think would get along well?
