Due to how powerful this masked human was and how he had been scaring her, Alicia had thought that Alex was an extremely old man who was almost at the end of his life and had taken a path in some dark magic experiment which was how he was able to use two elements instead of the usual one.
Also, topics like dark magic experiments were usually involved with hideous side effects such as the experiment affecting the face or causing health problems to the person involved.
This had further led to her imagination of Alex being an old man with a very scary or unsightly face, which is why he wore that white mask around. Plus, his scary attitude didn't help change her thoughts but strengthened them instead.
So when Alex finally took off his mask and revealed his face, Alicia was shocked beyond words upon seeing him. He wasn't some cruel-looking old man who was at the end of his life as she had expected; instead, he was a very handsome human male and looked extremely young!
