Dorothy: Wait a minute. There's one thing I don't understand. When I checked to make sure that Kendall was really dead, why didn't his breath show up on your mirror?
Rose: Simple. The mirror had been sprayed with defogger.
Dorothy: But who could have done that?
Rose: I did. The people at the club asked me to.
Blanche: Well, Rose, why would you do such a cruel thing to me?
Rose: Well, Blanche, there could be two explanations. Either I was getting back at you for taking my earrings or... Oh, who are we kidding? That's why I did it.
