WHY DOESN'T THOMAS TELL THE OTHERS ABOUT HIS TELEPATHIC LINK TO TERESA?

Thomas doesn't tell the others about his telepathic link to Teresa because he fears it could create panic or distrust among the group. He is also uncertain about the nature and implications of their connection, leading him to keep it a secret for self-protection and to avoid complicating their already challenging situation. Additionally, he may want to maintain a sense of normalcy and focus on their immediate survival rather than introducing new complexities.
