When quoting a comic novel, it's important to note the page number. This helps others find the quote easily. Also, if there are any illustrations related to the quote, it can be beneficial to mention them. They might add more depth to the understanding of the quote. Another aspect is respecting the author's intention. Don't twist the quote to fit your own agenda.
First, make sure to accurately transcribe the text. Any misquote can change the meaning. Second, consider the context within the comic novel. The words might have a different impact depending on what's going on in the story. Third, be aware of the style of the comic. If it has a unique dialect or writing style, try to preserve that in the quote.
