It's so interesting to me that even after ten years of living among Shadowhunters, Tessa still associates safety with mundanity. There's a contradiction inherent to Shadowhunter life, where everyone lives and dies and raises their families with the understanding that they will probably die young and definitely lose many of those closest to them. Tessa, I think, still hasn't adjusted to this way of experiencing the world. She doesn't want to comprehend that her family lives in the same city as vicious demons, because it means acknowledging that their sense of safety will never be complete. She can build a new life and start a wonderful family, but it will never be the same as the simple security that she had with Aunt Harriet as a young girl.
