While talking with media on the red carpet for the LA world premiere of Iron Man 3, Joss Whedon intentionally and happily confirmed that the first draft for The Avengers 2 script was complete and that - while Marvel pres Kevin Feige said things can change in six months - it would feature a pair of new characters he described as a "brother-sister act."

Immediately that led us to believe that Quicksilver and Scarlet Witch of X-Men fame, and early members of The Avengers in both the main Marvel Comics universe and the more grounded 'Ultimate' Marvel Comics universe, would be joining Earth's Mightiest on the silver screen. Various media outlets confirmed through inside sources that these were in fact the characters in question, one even going so far as to say they're already modelling Scarlet Witch on Oscar-nominated actress Saoirse Ronan.

IGN caught up with Joss Whedon himself during the ABC's Upfront, where his Marvel television show Agents of S.H.I.E.L.D. was picked up with a full-season order, and sought a little clarification on the matter. Whedon, who's not only writing and directing 2015's still-untitled The Avengers 2, but helping oversee all of Marvel's "Phase Two" movies lead up to it, confirmed that Quicksilver and Scarlet Witch are duo being introduced in the sequel.

"You know, they had a rough beginning. They're interesting to me because they sort of represent the part of the world that wouldn't necessarily agree with The Avengers. So they're not there to make things easier. I'm not putting any characters in the movie that will make things easier."

Reports indicate that the redesigned mutants (who won't be mutants in the film) will be of British origins as opposed to their fictional Eastern European origins as the children of X-Men villain Magneto in Marvel Comics. Is Whedon referencing other countries as not agreeing with the superhero/vigilante ideals or is he referring to the mindset that the heroes should be accountable for their actions and the resulting disasters (see: Battle of New York), a common sticking point in stories from the books? We have been told repeatedly by Whedon that The Avengers 2 will be a lot more person and that this time, he gets to "twist the knife" so to speak, when it comes to the team dynamic and relationships.

The next little bit from Whedon is based on spoilers from the ending of Iron Man 3. Don't read ahead if you've not seen the film yet.

Iron Man 3 Second Trailer Discussion

As moviegoers who helped Iron Man 3 reach a billion dollars at the worldwide box office (as of today) will know, Iron Man 3 ends with Tony Stark (Robert Downey Jr.) blowing up all of his suits and leaving his destroyed mansion behind as he speaks on how he's changed that he (and not the suit) is Iron Man. What implications does this have for his return appearance in The Avengers 2 if he's done with the armor? Whedon says that may not necessarily be the case:

"Well, I feel like in Iron Man 3, even though he said,  'I've changed' -- he blew up his remote suits, but I don't think anybody thinks he doesn't have one anymore. The question is, if The Avengers are called, does he show up? And the answer is, 'Yes!'"

What would cause Tony Stark to suit up and fight again? Would it be a personal threat to him or Pepper Potts again or would the urge to help others force him into action once again? Is he really done "privatizing world peace" or could some other plot line from the comics - like an out of control Hulk - pull him back into the fold since he's close friends with Bruce Banner (Mark Ruffalo)... and because fans still need to see the real Hulkbuster in action.

Iron Man 3 is currently in theaters, Thor: The Dark World on November 8, 2013, Captain America: The Winter Soldier on April 4, 2014, Guardians of the Galaxy on August 1, 2014The Avengers 2 on May 1, 2015, Ant-Man on November 6, 2015, and Doctor Strange sometime after that.

Let me know on Twitter @rob_keyes how you feel about Magneto's kids being redesigned for The Avengers 2!
