Silver gets to relive the moment he discovered that Lilia is not his biological father from Lilia’s perspective, with Lilia admitting that he had been vague on purpose as he didn’t have to courage to tell him the truth. Lilia asks himself, “When did I start feeling this way?”
Silver relates this story from his own perspective later on, saying that he had been devastated to learn that he and Lilia were not blood related and he had fled their house into the woods during a storm: “I couldn’t progress forward, and I couldn’t go back home. I was at a complete loss and just started crying. But Father came looking for me, and he carried me on his back all the way home, even as I cried.”
Silver says that their life-or-death situation in Lilia’s dream has him feeling “a little inordinately happy” because now he can carry Lilia on his back: “This time, I’ll be the one to take Father home.”
We also hear this story in Silver’s first birthday vignette, where Silver says, “I don’t think I’ll ever forget the smile he wore on his face that day. I’m no longer concerned about blood relations. I’m my father’s only son, now and forever.”
During the parade of memories from his childhood Silver says that he doesn’t want to see anymore, so it seems that they were being shown to him against his will.
Silver also sees the moment that he presented Lilia with the acorn bracelet from the beginning of Book 7, which Lilia called his “single-most valuable possession” and something that even Malleus envies.
Silver sees himself explain to Lilia how he crafted the bracelet with help from squirrels and a woodpecker because he learned from oak tree fairies that having an acorn charm means that he will live a long, healthy life. Lilia seems moved that Silver, a human, wants him to live a long life, and squeezes Silver tight while saying he is sure that he can live another thousand years, with father and son saying that they love each other.
(In Book 7 Lilia says he was aware of his magic fading long before Silver and Sebek were born, so it is likely he already knew he had limited time left by this point.)
Silver seems to have forgotten both that day and the bracelet, but the sentiment remains: his wish for the Wish Upon a Star event is for Lilia to live a long life, saying, “I often find myself wishing he could live a very long happily ever after.”
Silver questions why Lilia would lie about a bunch of worthless, shriveled-up old acorns being his most valuable possession and unilaterally decides that Lilia could never truly love the Dawn Knight’s son.
