Logan Walker wasn't from New York, much like her co-worker, Lindsay Monroe. Because of this, she and Lindsay somehow became friends, rather than acquaintances. Those who worked in the lab saw this almost immediately, which Mac Taylor was relieved to hear. His main worry was that, much like Lindsay, Logan would have a hard time adjusting to the new surroundings around her, but that wasn't the case. Also like Lindsay, Logan came from an area much unlike New York. While Lindsay was from Montana, Logan was from Georgia. Mac could only hope that Logan would become accustomed to this area as fast as Lindsay had. Logan also had a past that she would try to keep as hidden as possible, only allowing a few people truly know.
