(S03E08) A friend and I were talking about a third woman, one who's involved with a volunteer organization. "I want my donation to be therapy for her!" said the friend. This week's episode of The 4400 opens that delicious possibility: the ability to force therapy onto someone. Oh, were it only true! I totally would have stolen that lady's herbs, too.

As it turns out, the therapy isn't always beneficent. Three people commit suicide at the opening of the show, haunted too cruelly by figures from their past. This sends Tom and Diana into a quest to find the source of the hallucinations -- a brand-new street drug called "Blink" -- and quash their own demons, personified by Tom's dead father and Diana's old fiancé.

Speaking of fiancés. The plot took its most delicious turn yet.

(S03E06) Last week there were arguments. I said the wrapup was too neat. Some of you said no, I just didn't get it -- there was complexity. Things might not be as they seemed. And I'm happy to ring the bell of correct-ness. Ding ding ding! az1324 called it: Matthew was sent back from the future to work for the "other side." Whatever the other side, is.

Indeed, much to my delight we're given ever more conundrums in The 4400. It does seem as if Isabelle has redressed her "angel of death" moniker, although she is causing quite a bit of murder and mayhem as she turns the gifts of the Nova Group members against them. Perhaps we should replace the "of death" in her title, in fact, with "avenging."

Add Alana -- who through her work with students in the 4400 school, finds the man who killed her first husband and son -- to the list of AA members. And when we're talking 4400, AA stands for Avenging Angel.
