Gibbs came to Tony's house, not expecting to find y/n there. Tony had a sister, want by blood, but y/n was Scottish, she had a strong Scottish accent. Y/N was adopted when Tony was 13. Tony was going to go to work but y/n had kept him home, Gibbs wanted to know why Tony never came in for work. So when Gibbs walked into Tony's house, y/n was sitting on the couch, Tony was asleep. Tony was running a high fever and y/n had caught it before it had the chance to spread. This was Gibbs first time meeting y/n, and damn, Gibbs couldn't stop himself, y/n was hotter than he wanted to admit. Y/N didn't work at NCIS, y/n worked at the hospital as a Molecular Genetics Technologist and an Anthropologist.
