Would be cool if, after their attempted robbery, S.H.I.E.L.D. kind of sees potential in them and takes them in as "trainees". Sitwell and the new, older S.H.I.E.L.D. agent in Item 47 (I forget his name) can star Sitwell was criminally underused in Thor, and I wouldn't be surprised if no one even noticed him in The Avengers, so it'd be great to finally give him the spotlight a bit.
