Back in 2008, when Marvel Studios was preparing to launch their first self-financed feature film, Iron Man, they convinced Samuel L. Jackson to come in on a Saturday to shoot a quick cameo scene, one that would play after the credits roll. It was a fun idea for the comic book fans, but it was also one of the smartest ideas the studio ever made. The few words spoken by Jackson’s S.H.I.E.L.D. director Nick Fury opened the door to a vast Marvel Comics library and the first shared continuity in film, and so began the journey to The Avengers and the tradition of post-credits “button” sequences.

Iron Man 2 teased ThorThor and Captain America teased the epic team-up of The Avengers; The Avengers teased one of Marvel’s most dangerous villains in Thanos. With Phase 2 of the Marvel Cinematic Universe underway, the tradition continues and these bonus sequences have become a staple of the franchise and an expectation of the fans. For Iron Man 3, Marvel went the way of keeping the film standalone at every level and its post-credits stinger was just something fun, not focused on teasing the next movie on Marvel’s slate, but with Thor: The Dark World, there was a very important reveal. For the next film coming from the studio, Captain America: The Winter Soldier, rumor has it that it’s going to be a big one as well…

Where the latest Iron Man and Thor installments attempted to – very intentionally – offer standalone experiences to prove the strength of the brand and individual characters when not teamed with their Avengers cohorts, Captain America 2 brings moviegoers back into the thick of things when it comes to the mysterious S.H.I.E.L.D. organization. The sequel not only features two Avengers in lead roles, but teams them with another potential member of the team in Sam Wilson aka Falcon (Anthony Mackie). The film acts as a bridge of sorts between The Avengers and next summer’s The Avengers: Age of Ultron (watch the new Super Bowl trailer!) and so its post-credits button needs to be a biggie.

According to Lainey Gossip who claim to have knowledge of what’s coming after the credits for Captain America: The Winter Soldier, moviegoers will meet the two new Avengers joining the roster for Age of Ultron. We do know that with the film releasing in March for some markets there is a rough cut of the complete film, but how this source saw it or has knowledge of it is anyone’s guess. Regardless of the how, if they’re to be believed, they are dropping the bomb on who shows up:

 They’re calling them “The Twins”, the brother-sister team of Quicksilver and the Scarlet Witch, and they don’t look like any Marvel heroes we’ve met to date. Having seen them, I am really sad for Fox and the X-Men…

We’ve known since before Iron Man 3 hit theaters that The Avengers 2 writer and director was planning to introduce the “brother-sister act” of Scarlet Witch and Quicksilver, two of his favorite characters from the comics. They’re an interesting pair not only because of their powers – which have yet to be explained since Marvel cannot label them as “mutants” – but because they begin as villains of sorts, characters who don’t necessarily believe in how The Avengers operate. Since they’re an essential part of the story of The Avengers: Age of Ulton – played by Aaron Taylor-Johnson and Elizabeth Olsen – the Captain America sequel is the best place to have them cameo – especially considering the last film before The Avengers 2 is Guardians of the Galaxy and that takes place 95% in space and may not hit an audience as big as Cap 2.

From Lainey Gossip’s word choice, it sounds like the pair are going to have an interesting costume design, perhaps something a little more faithful to the books than what we’ve seen from Twentieth Century Fox’s take on the characters in X-Men: Days of Future Past. We’re now wondering if the characters and their backgrounds tie into the final stretch of episodes of Marvel’s Agents of S.H.I.E.L.D. on ABC. There is going to be some connection between the show and Captain America: The Winter Soldier, we’re just waiting to see if its meaningful or as thin as the Thor: The Dark World tie-in episode.
