As the proofreader/translator guy (soon to be ex, or now ex I guess, due to some IRL issues on my end) I can say with certainty that the original scripts I receive are incest free. The patch is made by someone else, a deviant personality who sees his mother naked on EVERY Rorschach ink blot they've ever looked at...
Altered Vision doesn't approve of or condone the incest patch but understands that, with the setup of the plot, it is easy to believe that it was intended to be an incestuous relationship.
Anyway, this means I am officially unofficially retired as a proofreader. LOL
