Dorothy's in a jam because you f a gambling addiction that up until now has never been mentioned. She misses job interviews because of that, preferring to go to the racetrack instead, and even tries to swindle Rose. As much as I try to sympathize with her (as she usually is my favorite character on the show), I can't because a lot of her actions are completely out of character for her. Rose is given a minor plotline, painting for the museum Blanche works at, while Blanche has issues deciding if she's going to continue to see someone she works with. But Dorothy's issue dominates the episode, and is wrapped up way too fast, and not in a convincing way.
