I gave you an example, by restructuring the sentenses. Your main problem (appart from grammar) is that you overexplain things that clutter the text.
Your paragraph comes after a dialogue, and you repeat TWICE "after what I have said"--you do NOT need to repat it, it is ALREADY CLEAR. repeating it makes the text more difficult and irritating to read.
Then you give a detail about the eye-color that clutters instead of imparting the image. If you want to focus on it, focus on it, but do not just throw it as a subclause in the middle of everything else. In other words, after you said that her eyes deadened, start a new sentence and dedicate a full paragraph to the description of her bewitching eyes.
THEN start a new paragraph and let your protagonist REACT to that dead gaze, experience it, emotionally follow up to it.
You also overexplain with "what she did was confusing"--it is better not to say that, it is better to write a paragraph which shows the protagonist's confision through inner thoughts or emotional reactions.
So, overall, try to break up your text in simpler senetnces with correct grammatical constructions and separate what is happening (Mother looks at the character, mother reaches out to smother them) from emotional feed from the character and clearly deliver that conventional feed between the actions.
