James Denton (Mike Delfino) does not appear in this episode.

Mary Alice: (voiceover) Once the tornado had passed, it began. A man gave his coat to a stranger in need. A woman shared her food with those just passing by. A teenager reunited a dog with its worried owner. These are the things that happen in the wake of any great disaster. People start to perform small acts of kindness. They do what they can to help. All the while knowing, it won't be enough.

(To Lynette after the baseball field's security guards catch her)
Mrs. McCluskey: Run Jane Doe, run!

Mary Alice: (voiceover) It had been seven days since a tornado devastated Wisteria Lane (Edie picks through the wreckage) and the residents continued to pick up the pieces of their lives (Susan picks up clothing). Some salvaged precious friendships (Susan and Bree smile at each other), some uncovered colorful histories (Lynette looks through Ida's belongings), others found challenges they hadn't expected (a doctor examines Carlos' eye). And then (Dylan cleans the fireplace; finds the note her mother tore up) there was one girl who stumbled upon the truth she'd long been searching for only to wish she hadn't. (Dylan pieces the scraps together; stares in surprise at what she reads)

Mrs. McCluskey: That's a lesson we all gotta learn over and over: Appreciate people while we still got them.

Gabby: I know this is bad but we have each other. We'll get married again and everything will be fine. For richer for poorer right?
Carlos: In sickness and in health.

(Susan smells a sock Bree just washed)
Susan: Oh my God! I wanna eat that!

Julie: Why did you agree to let her stay?
Susan: How do you say no to someone in need? (Julie doesn't respond) That wasn't rhetorical.

Bree: You can raise a man's hopes without satisfying them. I've done it all my life.

Bree: Andrew here, happens to be an outted and proud homosexual.
Orson: He's here, he's queer, and we're used to it.

Edie: Well, you should be saying, "Lynette, this could end badly, so you should start preparing yourself for that now".
Bree: Edie, if you say that to Lynette, so help me God, I will wring your neck!
Susan: And I will help her!

During season 3 we learn that Dr. Craig was Ida's nephew. Following her death in this episode, the nearest family that could come and take care of her things were from out of state, which is untrue since Dr. Craig lives in the area.
