I think how the text uses dramatic irony with the use of dramatic adjectives and other describing words. (sorry if I'm wrong I'm just not that smart)
It would be too obvious for me to write the entire letter for you, but I'll include a list of points that you could include in your own writing style:
* Thanking Lee for his letter, and saying that you are happy that he is having a good time.
* Telling him roughly what you're studying at school (without being boring).
* Write about what you would like to do when you leave school.
* Finally, say that you miss him a lot and look forward to hearing from him soon.
I think D; Loyal to his people and their cause.
Light bulb? i hope this is what you’re asking
