Caroline in the City 3x15

An unusual episode focussing on Del, who for once has an adult problem after he hears some shocking news from Laura, a former fling who's in town for the weekend - together with the daughter she had by Del but never told him about. Torn between a burning desire to meet his child and his terror of being a total disappointment to her, and Annie's brother quits his job to become a painter after he misinterprets Richard's evaluation of his work as an artist.
