It was another day at the NCIS office. Y/N has tourettes. (Tourette syndrome is a nervous system disorder characterized by tics, which are sudden, repetitive, and involuntary movements and sounds). The team knew y/n had tourettes, it was in her file. Today, when everyone was talking, thanks to a tic y/n ended up hitting Tony on the back of the head. Y/N stepped away from him trying not to hit anyone else because of a tic, she nearly did the same thing to Jimmy. And y/n hit herself on the chin (it left a bruise), thanks to a tic.
