sam got on S.H.I.E.L.D'S radar not in a good way at first because of something she did when she was younger and let's just say she did something that was pretty bad.... and shield sent agent clint barton to pick her up and bring her back to S.H.I.E.L.D. (I do not own any thing avengers other than the story line and my character sam.) THANKS FOR READING! ^_^
