While the song as a whole explores themes of heartbreak, betrayal, and introspection, this particular line sheds light on the idea of misunderstanding and the complexity of human emotions.One of the unexpected themes that can be derived from this line is the concept of empathy. The speaker acknowledges that there are traitors who don't understand, implying that there are individuals who may not fully comprehend or empathize with the pain and turmoil they have caused.

This theme speaks to the challenges of navigating a relationship with someone who constantly keeps you guessing and unable to fully grasp their true intentions.Furthermore, this line also touches upon the theme of self-reflection and personal growth. By acknowledging that there are "traitors who don't understand," the speaker implies that they have gained insights and understanding about their own experience. They have come to a point of self-realization, recognizing that they should have heeded the warnings from others when they said "Run as fast as you can." This theme emphasizes the importance of learning from past experiences and not repeating the same mistakes. It suggests that the speaker has grown wiser and more self-aware as a result of the pain and turmoil they have endured.In conclusion, the line "Who don't understand" in "Dear John" contributes to the overall themes of the song by exploring the themes of empathy, constant change, and personal growth.
