Episode: Season 9, Episode 10
What happens: Just like Ellis, Richard's wife, Adele, eventually gets Alzheimer's in season seven. (It's a recurring plot device, much like the series's number of tumors.) She ends up in a home, where she develops a romance with another dementia patient. In season nine, Adele is rushed to the hospital on the day of Bailey's wedding because of an aneurysm. Meredith and Bailey (yes, Bailey works on her wedding day because she's Bailey) successfully operate on her, but she later dies of a heart attack. We see Richard and Adele dancing to "My Funny Valentine" in a crushing dream sequence at the end.
