The good news for the Connor clan is that they no longer have to figure out what to do with Riley - Jesse was kind enough to fatally shoot her in the last episode. The bad news is that they now have to figure out what to do with Cameron since they think she whacked Riley. Between dealing with the murder of his girlfriend and weighing the fate of his killing-machine roommate, it looks like John's going to suffer some growing pains.

The series marks its 100th episode with a novel swap. Two families from previous episodes, selected by viewers, return to trade again.

The children of the two families exchange their thoughts at a kids' table meeting. l
* Jockeys (9:30 pm/ET Animal Planet)
The first season races to the finish tonight at the Breeders' Cup Classic as this up-close-and-personal look at the lives of jockeys, young and old, comes to an end.

* Numb3rs (10 pm/ET CBS)
Larry enlists the help of the Los Angeles Lakers' Pau Gasol and Jordan Farmar in an extreme effort to end CalSci's lengthy losing streak in basketball. But the real focus in this perplexing hour is whether a condemned mob boss committed the murder for which he is about to be executed. The death-row resident confessed to the homicide and still claims responsibility, even though new evidence strongly suggests otherwise. It leads to a moral dilemma for the team: Should they attempt to exonerate one of the most dangerous men in the mob?
* Battlestar Galactica (10 pm/ET Sci Fi)
One of the coolest things about Edward James Olmos is the man's voice: When he belts out a command or gives his people a pep talk, it resonates and sounds positively credible. It's a trait that comes in handy tonight as Admiral Adama solicits volunteers for what may very well be a suicide mission in Part 1 of "Daybreak."
