Stacy Keach plays Wendie Malick's father. In real-life, Keach is only 9 years older than she. Also, Keach took over the role from Hal Linden who originally played the character.
Victoria's dad (played by Stacy Keach) mentions playing Noah Wyle's mentor on ER. Keach did have a three episode run on ER but as Dr. Gates' (John Stamos) dad. He didn't share any scenes with Wyle who was no longer a main cast member by then.
In the previous episode, "The Young and the Restless" Melanie goes on a date with a Harvard dad, which indicates she already broke up with Jack. The episodes seem to be aired out of order.
