Years later, it is the star of that show, now a child actor gone bad with a history of detox and people always saying, I thought she was dead, Francesca Lanfield, who connects the two of them, after years of near-misses and almost encounters.

When Gwen decides to crusade to save Francesca's building, she writes letters to the newspaper which catches Nick's attention - and wins his heart.
