Love this story! You've solidified Jack as intelligent, thoughtful and a hero in his own right. I love how many heroes there are in LnC fan fiction. Some are quiet, unassuming like Clark and others more splashy like Superman. And now your Jack has stepped into being a hero, working from the shadows and underground Metropolis, turning skills as a thief and his connections into a good deed. Could this be a harbinger of Jack's future?
And he definitely needs a new start far far away from Metropolis.
