Over on M.A. Larson's personal webpage the episode title for episode 12 of the season has been revealed with Larson himself as the writer. According to a certain list that leaked a few months ago, the episode name matches so far!
While we don't know the air date of the episode or what it is about, it does add more credibility to that list! The name of the episode?
"Amending Fences"
Thanks to Andrew, Impus and Johnny for sending it in!
