Alright, so I haven't seen it in Secret Invasion yet, but do you guys know how Maria Hill ID'd scrolls in the comic books? She would take blood samples out and then kill, essentially kill the masking agent in the blood, and then the blood would turn green if it was a scroll. So she went around and collected blood samples from all the Avengers, and she figured out that Black Widow was a freaking scroll by doing that, so hopefully they bring that to the show, because maybe that'll make the show suck less.
