Character Arc
Anne Glass is a pediatrician who becomes the primary medical officer for the 2nd Mass after losing her own husband and young son in the invasion. With no combat training, she channels her grief into keeping the survivors alive, treating wounds, illness, and the trauma of life under alien occupation. Her steady presence and compassion quickly make her indispensable to the group.
As the series progresses, Anne grows closer to Tom Mason, and the two form a romantic partnership that becomes one of the emotional cores of the show. She gives birth to a daughter, Alexis, whose unusual development tied to Espheni influence drives a major and unsettling storyline, forcing Anne to confront fears about her own child and the nature of the enemy. These events push her from purely a healer into someone willing to take desperate action to protect her family.
Across five seasons Anne balances her medical role with a fierce maternal protectiveness, surviving capture, loss, and the strange consequences of her daughters fate. By the finale she stands alongside Tom as part of the leadership that sees humanity through to the end of the war, representing the resilience of those who hold a community together through care rather than combat.
