Friday afternoon, long-running children’s animated series “Arthur” (WETA Kids at 4 p.m.) kicks off the spring season with a bullying-themed episode, as Arthur makes fun of his friend’s sweater (all in good fun, of course) and hurts her feelings. “While we have seen a renewed focus on anti-bullying efforts over the last couple of years, most resources are targeted towards older children,” said executive producer Carol Greenwald.

FINALE WATCH: “Kitchen Nightmares” (Fox at 8). Status: Unknown. Gordon Ramsay wraps up Season 6 with a trip to Scottsdale, Ariz., to help a baking company that doesn’t have any trouble with cleanliness — but whose owners refuse to listen to constructive criticism about food and service.

FINALE WATCH: “Vegas” (CBS at 9). Status: Unknown. Things are still up in the air for a renewal on this drama, and the odds are questionable given that it was moved to Friday nights. In the first season finale, Sheriff Lamb teams up with Savino to get revenge on the man who killed his wife; later, Jack catches Mia in a compromising position.

FINALE WATCH: “Touch” (Fox at 9). Status: Unknown. The Kiefer Sutherland series landed a second season, although there’s still no word from the network whether the series will continue for a third.

FINALE WATCH: “Blue Bloods” (CBS at 10). Status: Renewed. This drama, starring Tom Selleck in a New York City police family, has proved to be a solid Friday-night performer and will be back for Season 4. The Reagans joins together to take down a gang leader when someone close to the family is murdered, and Danny gets a lead from the leader’s girlfriend.
