The sentence having lived with her for a year Chad studied eyes across the table realizing he had never clue about what make is narrative voice?

Here's why:

* Third-person: The sentence uses "he" and "his" pronouns, indicating a narrator who is not a character within the story.

* Limited: We only see into Chad's thoughts and feelings. We know what he's observing ("studied eyes") and what he's realizing ("never had a clue"). We don't have access to the thoughts or feelings of the woman across the table.
