So Marvel has launched a new app called "Avengers Initiative: A Marvel Second Screen App" as part of the marketing lead-up to the film's Blu-ray/DVD release in September. According to Collider:

The app will give users access to exclusive content leading up to the release of The Avengers on Blu-ray/DVD with new downloads available bi-weekly in July and August, with weekly updates in September.  The content includes “special access to the S.H.I.E.L.D. database, becoming a S.H.I.E.L.D. agent, invitations to “special missions” either remotely or in the field, links to character profiles, stories and scenes, interactive Marvel digital reader comic books and more.”

But that's just background. No, the real news here is what one of our fellow shippers discovered in Natasha's user profile. For screen caps and a full transcript of what I'm about to excerpt, check out sassassin-d's Tumblr post. Here are a couple juicy snippets:

Innnnteresting, yeah? Love the "functioning partnership" and "played a key role in her escape" lines. Plus, we now know the name of their group, which is pretty badass. And then there's Abidjan... What say you all?

(Aside: I definitely recommend downloading the app if you can. It's interactive and very cool--you can even watch a clip of Natasha shooting in footage from a battle. Only Steve and Nat's profiles are available now, but I'm sure we'll get Clint's soon too.)
