“You thought the end was nigh? Think again?”
I… Don’t recall having seen this promo poster for Season 4. It was at the bottom of a recent article much like all those other articles on why Mark says there might not be a season five, which is ironic considering the tagline. I don’t know if this is fanmade, but I don’t think it is considering it was in an article.
Also Moriarty’s revenge? What is there to avenge if he is dead? Unless he is a she and she is Mary.
Here’s where I found it on the article page. And the link to the article. it is from comicbook.com and the article is just a reiteration of every “Benedict and Martin’s schedules don’t match so they won’t be able to film blah blah blah”.
EDIT: THIS IS FANMADE AND REALLY WELL DONE. IT IS BY @tj-teejay SOMEONE POINTED OUT AND IT LOOKS LIKE WHOEVER USED THIS ON THEIR WEBSITE TRIED TO GET RID OF THEIR URL ON THE RIGHT HAND BOTTOM CORNER K THX SORRY.
