Book Reports / Differences and similarities between Oedipus and Brick(Cat on a hot tin roof) [4]

Hi,

I'm having a hard time creating my outline (for tomorrow!) and I need your help. I will have to write 1200-1500 words on the following topic : Compare and contrast any 2 of the plays studied in class based on theme or character or symbolism. Since it's an open subject, I decided to write about Oedipus Tyrannos, by Sophocles, and Cat on a Hot Tin Roof, by Tennessee Williams.

I would like to discuss 2 similarities and 2 differences (so 4 body paragraphs). I started to analyze the characters of Oedipus and Brick and this is what I found:

Similarities:
1-Oedipus and Brick both receive the help of 2 people to bring out their real nature (Oedipus = Creon and Tiresias, Brick = Maggie and Big Daddy)
2-Oedipus and Brick both fall into problems after they discover the truth (oedipus blinds himself, Brick get into alcoolism).

Differences;
1-Oedipus ignores the truth and wants to know it.
2-Brick knows the truth but wants to ignore it.

** I think that my 2 differences could go together but I don't know how to write the sentence. And it would imply that I have one missing difference ... can you help me find ideas ?

Thanks in advance

Karina
