Moving from Germany from when she was a late teen, Mathilda always had a fascination with the world of nature around her. Owning many animals in her lifetime and spending her free time at zoos, she seemed to always surround herself with animals more than her fellow human. Because of this, she seemed more distance from others, causing her to delve into her studies even more. Medic and Mathilda both met at a collage overseas, with them both connecting over their personal projects and their share interests over the macabre. Over time, they grew closer and closer, with her getting him a steady supply of animal organs and him getting her new tools and organs from the human body to study. Once collage finished up, both of them got married and settled down in the countryside in England. Both happy with stealing birds from a prime minister and adopting a wild cat. People called them inseparable until Medic left for America for the Gravel Wars.
On the outside she appears cold and stern but gets a lot more wild and free when she's happy / doing her “personal projects”. Usually has poor people skills with appearing standoffish. When she's happy, she gets really frenzied and excited, info dumping all about herself and her “pets”. She loves animals and cares for them deeply. She even helped install a device in Medic’s doves, so they could survive greater blood lost. The greatest flaws for her is having trouble finding her own self-worth and mainly needing to be more open to others. Other main flaws is her being extremely petty and holds grudges easily when she's wronged in even the slightest of ways.
