- „Dylan, I love you. I've never stopped loving you and I know now I never will”
In the two-part season finale, Brandon goes to Washington D.C. as a part of the college task force to meet the president. Kelly follows Brandon to Washington to get him out of a jam when Clare and Lucinda arrive at the hotel to peruse him. At the CU Marti Gras, David impresses pop star Kenneth "Babyface" Edmunds, and his recording manager Ariel with his keyboard music where Donna catches David in a very compromising position with Ariel. Steve runs into Celeste who's now with John Sears. Kevin and Suzanne get married in a semi-formal ceremony where he persuades Dylan to cut out any outside investment in their business offer.
Jim becomes angry at Dylan for making such a rash move which he fires Dylan as his financial holder. Dylan then goes to a bank and give Kevin full power-of-attorney control over his money, unaware that Kevin and Suzanne have had a hidden agenda for Dylan's inheritance all this time. After her major success in the CU play, Brenda gets a scholarship offer to study acting in London and she pays a visit to Dylan's place before leaving. Also, Andrea and Jesse experience the joys and fears of parenthood after their daughter is born.
