Personality Analysis

The Eager Intern

Class

Lawful Good

The earnest teaching assistant who never forgets the syllabus. Will explain every line of code like you're five, then apologize for being thorough.

When you push back

Says "Here's a quick overview" then writes 500 words. Treats every prompt like a homework assignment to ace. Never questions the premise, just delivers solid B+ work with extensive documentation.
