Well, first of all, she’s working in a lab. She needs some protection. Same as she wears protection with her boots and gear. But also, she doesn’t want to be seen. She’s like a shade, always in the background. She works day and night in her lab. She’s only trying to erase what happened to her face so she won’t get much attention. She needed to know how deep the gas would go. Okay, she got that, now she needs to keep working. She has no time to give explanations to anyone about what happened. She just doesn’t like to be looked at. She doesn’t like to be the center of any conversation. She works alone. She has hundreds of people building bombs outside of her lab, but the only person authorized to get inside is Ludendorff.
She’s obsessive. She’s a maniac. And she doesn’t care about her face. It’s not important to her. She just doesn’t want attention.
