The final sentence was Simon Carrington actually explaining that his previous words were indeed serious and contained no joking. He truly liked Daisy Willow and admired her, which was why he had made such a suggestion.
However, they were all parents now, probably unable to express love as openly as young people do.
But Daisy Willow completely failed to realize that the final sentence was the main point Simon Carrington wanted to relay. She was shocked by Stella Carrington's background and also by Liam Carrington, who had actually come into this world through artificial insemination.
How profoundly must Irene Houston have loved that man, to remain chaste for him even though she was married to someone else?
No wonder she had been so casual about divorcing Simon Carrington. It seems that aside from worrying about Stella, she really wasn't too concerned about anything else.
