Symbolism, Imagery, Allegory
Go Fish
This symbol is only slightly less transparent than Millard the invisible boy.
When diving deep into the shipwreck, where no one else will venture, Emma and Jacob find a glow-in-the-dark school of flashlight fish. Emma explains their symbolism for us, point blank: "They hide" (8.282), she says, and "They're peculiar" (8.285). Gee… that sounds an awful lot like some kids we know.
Plus, the journey to visit the fish mimics Jacob's journey to Miss Peregrine's home. He goes somewhere no one else dares to go (through the cairn) and ends up in a world full of fascinating creatures that not many people know exists.
The symbolism might not be complicated, but Emma's description is more than enough for Jacob to lead to more smooching. What can we say? Metaphors are romantic.
