It's All About "One"

Yet another fabulous episode of Sopranos tonight. Every Sunday this show just keeps getting better! So here's the rundown: Tony goes back to "work," and hires a Bloomfield meathead to drive him around. Johnny Sack's daughter Allegra (Chris, it's allergy medication, not cold medication) is getting married and Johnny requests a reprieve from his jail cell to attend. The court grudgingly allows it, but makes Johnny foot the bill for the US marshals that have to chaperone him. The Soprano family goes to the wedding, and Tony is feeling a little wistful for grandchildren, which he expresses to a less-than-amused-looking Meadow. Which, by the way, as a sidebar, Meadow is looking absolutely stunning this season. Looks like there might be trouble in paradise with her and Finn though; but I digress.
There is tight security at the $425,000 Sacramoni wedding, and Tony nearly passes out when security makes him take off his shoes. Johnny asks Tony to "take care of some business" for him, using a table of partially senile senior citizens as a ruse for the marshals, and Tony agrees. Just as the wedding is wrapping up, the marshals come and haul a bawling Johnny back to the prison, and Ginny hits the floor. Literally. I liked the shot of the knee highs. Funny how the show can make you pity a cold blooded murder and start making you rationalize the idea that he might be entitled to watch his daughter get married in peace.
Anyway, Tony starts to worry, after talking to Melfi, that his recent health problems might appear as a sign of weakness. As a result, he beats up the meathead and subsequently vomits in the bathroom - but hey, people only see what you want them to see.
Meanwhile, Junior is thrown into a mental facility and tries to argue with his lawyer that he doesn't belong there. Right.
The highlight of the episode, however, comes when Vito tells his wife he has some "collections" to do late in the night. Those collections, however, entail donning a leather outfit and heading to a homosexual club where he's having a hopping good time. That is, until a couple of mob friends drop in for some business, and catch Vito in the act. He tries to play it off as a joke, but of course they're not buying it. A distraught Vito goes home, packs the suicide essentials, and checks into a motel. He makes an erratic call to Silvio, and that's the last we see of poor, repressed, Vito.
I guess we can assume that he, er, lost his head?
