comment_fic is so handy for character studies and small amounts of writing. So!
Supernatural, author's choice, Thomas' faith in anatomy was stronger than his faith in faith (Dickinson) A Gabriel character study, which does clash with fanon!niceguy!Gabriel, I believe. I keep seeing fics where Gabriel's a much kinder power than you see in Tall Tales, Mystery Spot and Changing Channels.
And honestly? I don't think the 'Chesters changed him that much. And while he might be an angel who cares about family, I can't see him becoming a perfect gentlemen (or even an abrasive but generally harmless person) if he falls in love.
Which leads to a whole bunch of other things, but yeah. Fic! That's what we're here for.
