Stunned, Stephanie worries how the daughters will react to this news and what follows to their mother.

While Marcus helps comfort a shaken Beth, Stephen pulls Donna, Katie and Brooke together to tell them that Beth is in stage 5 of Alzheimer's disease.

He goes on to talk about how frustrated she'll get as she can't remember things. Brooke guesses that anger is a symptom of this horrible disease. When Beth returns to the room, Stephen tells her that he wants to marry her because time is precious.

Thanking him for asking, Beth tells Stephen that she can't marry him. Pulling out a ring box, Stephen tells Beth that he bought the ring in Paris months ago before he knew anything about her disease.

He denies doing this because of guilt and reminds her that no one knows how much time any of them have left. Thanks to Katie, Brooke and Donna pushing her, Beth accepts his proposal.
