The AI-generated response took the question literally and could not infer that you might be looking for a literary analysis of the vernacular in the quote. 

Here is an answer that assumes you'd like to understand more about how the choice of wording speaks to the characters and their circumstances:

From a literary perspective, this statement operates on multiple levels and reveals significant character information through its deliberate grammatical construction.

The non-standard phrasing "weren't easy confused" (rather than the grammatically conventional "weren't easily confused") suggests several interpretations:

1. Vernacular Voice: The statement likely represents a specific narrative voice using regional or cultural dialect. This unconventional grammar creates authenticity and establishes the narrator's background or perspective without explicit exposition.
2. Character Development: Through this economic phrasing, the author simultaneously establishes two characters (Kamata and Alvillar) while defining their primary trait - mental clarity or resilience. The description suggests men who maintain composure and clear thinking under pressure.
3. Implied Backstory: The statement implies these characters have been tested or faced situations that confuse others. Without explicit detail, it creates narrative tension and hints at previous experiences that have developed this trait.
4. Cultural Coding: The distinctive surnames (possibly Japanese, one Hispanic) paired with colloquial phrasing suggest a multicultural setting and potential identity or cultural intersection themes.

In literary contexts, deliberately crafted "incorrect" grammar often establishes authenticity, creates a distinctive voice, and economically layers meaning beyond what standard phrasing could achieve.
