For fic author Never Have I Ever: have you ever written a fic that changed your opinion of a character?
ooooohhhh what a great question!! i'm not sure i really have, because 1) my fics tend towards the short side, so there's not enough space for the characters to start running off in unexpected directions and 2) if i decide to write a particular fic it's usually because i have an Agenda about how the characters would behave in it XD
butttt maybe this counts: there is one kinkfic that i wrote, about davies/horne/acaster behaving about how you'd expect them to (horne is a tricksy fuck, acaster blunders right into it, davies metes out punishment), where i was in two minds about which direction to take it - whether to make greg Angry and Scolding and Fearsome, or whether to make him just find the whole thing hilarious and deliver the punishment as an additional cruel mischief...
i chose the former, but often i think back on it and wish i'd chosen the latter, because greg so frequently gets painted as Angry and Scolding and Fearsome, but honestly i think he's much softer and cheekier AND particularly a lot more fun-loving than that, and i should have let him enjoy himself a bit more (and be a bit more three-dimensional)!! playful teasing doms ftw :P
(i'd be intrigued to hear your answer btw - i suspect you'd have a richer perspective - so consider yourself inboxed if you would like :D)
