OK, you knew WB couldn't keep them apart. Even if Buffy and Angel have been separated forevermore, you knew their respective shows would remain linked. Tonight's story will play out over both programs. First, on "Buffy the Vampire Slayer" (8 p.m.-9 p.m., WNUV, Channel 54), Oz (Seth Green) travels to Los Angeles, in an adventure that continues on "Angel" (9 p.m.-10 p.m.). Even better news: Spike (James Marsters) will be seen on both shows tonight, seeking a mythical relic that makes the owner invulnerable, and then regularly on subsequent episodes of "Buffy."

"Nova" (9 p.m.-10 p.m., MPT, Channels 22 and 67) -- Modern technology sheds light on an infamous 1954 murder in which Dr. Sam Sheppard was convicted of killing his wife. PBS.
"Sports Night" (9: 30 p.m.-10 p.m., WMAR, Channel 2) -- William H. Macy, real-life husband of cast member Felicity Huffman, begins a multi-episode guest stint as a ratings expert who does what ratings experts do -- tries to get more people to watch -- much to the consternation of the "Sports Night" staff. ABC.
"Frontline" (10 p.m.-11: 30 p.m., MPT, Channels 22 and 67) -- "The Lost Children of Rockdale County." Affluent but bored teens in Georgia turn to cynicism, drugs and multiple sex partners -- and cause an epidemic of syphilis.

"Biography" (8 p.m.-9 p.m., repeats midnight-1 a.m., A&E;) -- Fred Gwynne became well known with his series "Car 54, Where Are You?" and "The Munsters." But that was no guarantee of future success; for years afterward he was able to get only bit parts.

"The Greatest Supermodels" (9 p.m.-10 p.m., repeats midnight-1 a.m., The Learning Channel) -- They may be paid as much as $25,000 a day, but, this program tells us, it's not necessarily an easy life. All that jet lag, for example. Among the models who talk about their work tonight are Christie Brinkley, Cindy Crawford, Iman, Elle MacPherson and Tatjana Patitz.
