Dr. Cassandra Lin. Alias: "The Surgeon" (unofficial, used by some staff). 30. Head of Biological Anomaly Studies. Brilliant, clinical, and unnervingly composed in high-stress situations. Often seen as cold or detached, though colleagues note flashes of dry, dark humor. Obsessed with her work, bordering on unhealthy fixation—she speaks about anomalous biology with the passion of an artist. Rumored to enjoy dissections more than is strictly professional.
