Questions About "Just Add Water"

I just want to say that I really want to see how this movie ends, especially after watching the part we watched last class!

1) What's up with the wife? Why is she so withdrawn? Is there something mentally wrong with her or is she like this because she's doing something behind his back?
(I asked this before we watched the second segment. She's having an affair, and that's at least partly why she had always been withdrawn.)

2) I don't know if this is significant at all, but what's in the tin that Ray has in the car?

3) How does Dike manage to run the town? Are their any law enforcement people around who would be able to stop him from cheating people out of money like he does?
(This question was also answered in the second part. The town was declared a toxic waste site, and instead of moving out, Dike bought all of the property from the government for a very cheap price. Since he now technically owns the town, he decided to charge anyone who wanted to continue living in the town.)

4) Toward the end of the last scene we watched, Danny DeVito's character urged Ray to go for his dream of re-establishing the town. Is this something Ray is going to attempt to do throughout the rest of the movie? Is that where the significance of the title comes into play? Will that be Ray's solution for the town?

5) Are Ray and Nora ever going to get together?!

6) Why is the town in shambles? What happened to it that made it so desolate?
(Again...this was also answered. The state diverted the water and it then became a chemical run-off area. The state declared it a toxic waste site and strongly suggested that everyone leave.)
