Sebek takes his frustration with the loss of Malleus’ parents out on Silver in Book 7, declaring that he must join Lilia in protecting Maleanor with his life.
Silver reminds him that they are in a dream where nothing they do will change reality and Sebek again questions if they cannot just stay in the dream, where Malleus can live with his mother and Silver will be able to live with Lilia.
Silver fails to come up with convincing argument and Sebek is nearly swallowed by the darkness, saved by Silver.
Silver asks, “What would happen to Malleus, crafting these dream worlds in complete solitude?!,” and Sebek points out that Lilia will only be waking up to die, but Silver says, “He’s want to anyway. I know Father would advise against what Malleus is doing right now. A retainer isn’t there to simply be a yes-man to their liege. Sometimes it’s important to speak out against them. Surely father taught you that, right?”
Sebek declares that he will never second-guess himself again, and Silver says that he had best not break his word. (Sebek: “Hmph! I need no warnings from you! *sniffle*”)
Sebek is able to repay Silver later on, using his unique magic to save Silver from the darkness of his own mind. Silver swears that he will never lose his way again, and Sebek says that will hold him to that promise.
In a rare moment of agreement Sebek says that summoning a sword would be more practical than being able to summon cups and kettles, as “that way you could squeeze in some training anywhere, anytime. Silver responds, “For once, I like the way you think.”
They also join forces during Tsumsted when Silver says he hopes that Lilia and his tsum do not cause a commotion on campus, suggesting that he and Sebek go check up on them together. Sebek agrees.
