Option #1) Find a very confusing passage in House of Leaves - not a slightly difficult one, but one that drives you up a wall. Hopefully that won't be too hard! Then, briefly explain both
a) What that passage seems to mean, or at least one possible explanation of it. If you're highly confident in your explanation, your passage is probably too easy (or you did some substantial research).
b) What that difficulty accomplishes; in other words, you should explain what the difficulty itself (think form, not content) is for.
Option #2) Discuss some element of the _form_ of Jimmy Corrigan in relationship to some element of the _form_ of House of Leaves. You should discover at least a tentative argument, and refer to a specific passage/panel/page from each book.
