7 Ways Deadpool 2 Sets Up Future Sequels
3. The Essex House For Mutant Rehabilitation
In Deadpool 2, Firefist, AKA Russell, has a vendetta against the orphanage he was bought up in for its continued abuse of mutant children. Mistreated at the hands of 'sex-offender-lookalike' headmaster Eddie Marsan, Russell vows to kill him and destroy his property in the process - which to be fair to him, he very nearly does. It's the name of the institution that serves as most poignant however - The Essex House for Mutant Rehabilitation.
Where have we heard that name before? Initially, in X-Men: Apocalypse during a post-credits scene, where a vial of Logan's blood is taken away in a briefcase marked Essex Corp. The link between these two references comes from the comic books, possibly seeding a new villain in the form of Nathaniel Essex, better known as Mister Sinister.
A supervillain obsessed with genetics, mutant powers, and Jean Gray and Cyclops, he meddled his way into getting the pair to birth a son. That son's name being... Cable!
The build up to Mister Sinister seems to be slow and steady so far, but with multiple references to his name as well as Cable being introduced and a Jean Gray feature film being released next year, it seems inevitable he will be rearing his ugly head later in the series. Or even SHE will be rearing her ugly head.
Rumour has it Mister Sinister might be appearing as the gender-swapped Miss Sinister, antagonist to the aforementioned Jean Gray movie. With Jessica Chastain attached and some shapeshiftery on the cards for her character, it's only a matter of time until we find out where Essex is hiding...
