Clearly Carter's just turned someone's offer down. Unfortunately for her, and fortunately for him, when you're that size, heavy weaponry would be required to change his mind.

Animation by  neodokuro, who pretty much surprised the hell out of me by doing this. Vocals are from Mass Effect 2, specifically the turian guarding the quarantined area in Mordin's recruitment mission. Oddly, I really like this voice for Carter.
