At the begining of Prince of The Elves, Karen is helping Naving get into his new uniform when he says, "I look like a waiter, Mom." AND THEN LATER he actually gets to be a waiter XD i love it!
I was re-reading the part where Trellis goes into "the void" (but it's actually his memories). Vigil gives him a robe to wear that belonged to Vigil's father, who was "the village healer, a doctor." Could this be foreshadowing? Like, maybe not that Trellis will be a doctor, but that he will save someobody? The nation of the Elves? Emily?!? Let's be honest, porbably Emily. They are constantly saving each other.
And perhaps it may have already been fulfilled, when Trellis "bubbles" the elves from Max's ship with the help and Emily and Vigo. Cause they saved all of them!
Have you guys noticed any other clever foreshadowing?
