itachi was a member of the akatsuki. he had orders to capture you. for him it was simple because when he saw you you were lying collapsed on the ground after an exhausting mission and you were sleeping, unaware of the shady figure in front of you. he takes you like a bride and starts walking

itachi: to himself I'm a little spaced out... she was so blissfully lying on the grass- what the fuck am I ranting about?! It's a miserable mission! you must not let me influence you!
