In her final words on CBS' "The Young and the Restless" as Katherine Chancellor (aired on Friday, May 3), Jeanne Cooper says to Jess Walton's Jill Abbott, "I believe I can manage. Thank you, though," when Jill asks if Katherine needs help getting up the stairs. Katherine's final word was "Goodnight" as Jill watched her climb up the steps. Word of Cooper's final scene came to light courtesy of "Y&R" script editor Brent Boyd on Twitter.
