“Everwood” (8 p.m., WB) wades into controversial territory with an episode devoted to a teenager’s pregnancy and her father’s insistence that Dr. Brown (Treat Williams) perform her abortion. While cynics might deride this as a “very special” “Everwood” episode designed to get attention and ratings during sweeps, the show’s creators have produced a fairly intelligent hour of television that deserves attention.

The friendly rivalry between Drs. Brown and Abbott (Tom Amandes) provides a forum for a surprising conversation that looks at several sides of a complicated issue. A weak subplot about Delia’s (Vivien Cardone) discovery of a “dirty” magazine is a bit much given the heaviness of the central story, and fans of the ongoing Ephram-Colin-Emily soap opera will not be disappointed. I won’t give too much away here, but at the end of the hour we learn much that is revealing and thought-provoking about two major characters on this superior drama. Look for “Everwood” to lose advertisers and earn some praise for this episode.

Tonight’s episode of “Everybody Loves Raymond” (8 p.m., CBS) sets out to prove that “it’s the little things” that often come between husbands and wives. After a pleasant weekend vacation, Ray and Debra engage in a silent war of nerves over who will pick up the suitcase and put it away. As usual, Marie provides perspective when she recalls a silent battle she has been waging with Frank for the past 45 years.

David Duchovny narrates the four-night adventure miniseries “Eco-Challenge: Fiji” (9 p.m., USA). Eighty-one teams representing 23 nations traveled to the Pacific island to compete. The “challenge” calls on them to climb a 1,000-foot waterfall, trek through thick jungles and swim in the open sea. Participants include celebrities major and minor, including “Star Wars” actor Hayden Christensen, a few “Survivor” and “Road Rules” castoffs and a team of former Playboy playmates sponsored by a vodka bottler. May the best product placement win.
