NCIS Season 15Edit
Sloane is introduced in "Skeleton Crew (NCIS episode)", where she appeared at Gibbs's door in the middle of the night, during Hurricane Molly. She wanted to use his phone as her car broke down and her cell was dead.
Prior to joining NCIS, she was in the Army. At the time she was captured in Afghanistan, her rank was Lieutenant.
As a result of being held captive for nine months in Afghanistan when she was a POW, she has multiple scars on her back.
She can profile anyone, and she may deny this but she profiles her friends on her spare time. She can fight extremely well considering all of what she’s been through.
