If the Dragonborn sides with the Imperial Legion during the Civil War, she says, "Talos guide you," revealing her religious beliefs despite being part of the Legion. She also whispers "Talos be with you" to Ulfric Stormcloak after he is killed, only for General Tullius to react with alarm.

Her coffin can also be found in the Solitude Catacombs with General Tullius.
