Maria was immobile, she couldn't respond to stimuli after waking up from the hospital. She was transported back home by Jerry, and had walked into the house to see everyone's worried face.
Especially that of Axel, who she didn't know if he was really sorry about what happened, or was he relishing in the fact that William was out of their life. Afterall, he isn't his son.
Lady Catrina was another story for another time, she didn't look fazed for someone who had been warming up to William. If anything, if Henry wasn't on her side, she would have suspected that she has something to do with him kidnapping their child.
Maria was annoyed at everyone but she didn't exclude herself either. Lady Catrina had forbidden her from doing anything, that would alert the media about her son's disappearance. Everything was just business to her. How could she forget what sort of a person she was?
