The lovely and hilarious Cobie Smulders was on Letterman last night, along with a new Avengers clip that finally shows Smulders as SHIELD agent Maria Hill. Talking, even! Specifically, she's talking to Nick Fury, who's scolding her for pointing out how fucked everything is instead of doing something useful, although if everyone's going to blow up anyways I wouldn't want to waste my time trying to evacuate people either. Let 'em get incinerated in the comfort of their own homes, that's what I say. FYI, I think we can assume the "tessaract" being discussed is the Cosmic Cube, so there's a little more confirmation of what we already knew. Thanks to Michael E. for the tip.
