I was looking for some fanfics based on this episode and could not find any at all listed in the Archive Database with a keyword of "Episode-Related" to this episode.
Michael Haney has a fic,
Just One Bad Day Away where "Deadshot" makes an appearance. Deadshot was hired by Deathstroke, who in this fic is Slade Wilson. I like that Batman makes a cameo appearance as well.
And Ultracape, over on Annesplace.net, in the nfic section, wrote
Endurance Testing , where Clark's heart is affected by Deathstroke's powers. Smut is involved.
I looked for this on the nfic boards of this website but could not find it here.
