Nathan and Emma and Hellfire, oh my!

Josh Wilding at ComicBookMovie.com in Who Is Nathan Milbury In Marvel Studios' X-Men Reboot? Adam Driver's Sinister MCU Role Explained:

Milbury is one of the many aliases used by the man who would become Mister Sinister. While this could be Marvel's way of playing coy with the identity of the movie's big bad, there may be considerably more to this iteration of the character than meets the eye. 

This article is chock full of interesting info on Mr. Sinister. There’s some great comics depth there. One of the things that caught my eye was the connections Wilding drew to the Hellfire Club.

Driver was rumoured to be up for the role of Sebastian Shaw, but what if Milbury is connected to the MCU's Hellfire Club? When Essex encountered Apocalypse in the Victorian era, he took him to the Hellfire Club, hoping the influential secret society might take his theories about evolution seriously. With Emma Frost, a.k.a. the White Queen in this movie, that organisation could come into play.

I have been thinking about Emma's role in the film, too, and a potential encounter with the Hellfire Club. I didn't know about Sinister's relationship to the group. That connection makes me think this take might be correct.

Emma Frost has to be a villain in her MCU X-Men introduction, right? Maybe she and Sinister are a fledgling version of the Hellfire Club. There could also be hints to a longer history for the villainous organization. With this good looking cast, we might even get a version of the Hellfire Gala. As popular as the Krakoa Age of the comics has been, it wouldn’t surprise me to see at least some nod to that recent era in the comics.
