This scene clearly lays out the symbolism of then color white in the book, with Clare explicitly tying it to the promise of a fresh start. The couple is hopeful for the new possibilities their child might open up for them, but as the novel has shown numerous times before, it’s very rare to have a completely fresh start. It's plausible to predict, then, that Clare and Henry are being unrealistically optimistic about the future. A baby likely won’t halt Henry’s time travels, and it’s a distinct possibility that the baby may inherit Henry’s condition, which would only add to the family’s struggles.
