History[]
Four years before the current premise of Amulet, David, Emily, and Karen are on their way to pick Navin up from a unknown destination, a drug cartel. Along the way, David tries to avoid hitting a person who had a broken down car. The car drives off the railing and tumbles down a steep hill. At the bottom they crash into a tree that is next to a cliff. David becomes stuck under the dashboard of the car and the car starts leaning against the tree and sliding towards the cliff. Karen and Emily escape, but they can't save David, because his legs were stuck under the Dashboard. who falls off the cliff along with the car and dies falling into the city below.
Firelight
In Firelight, we see David again as a memory in Emily's dream. Later at the end of the book, in the memory, Ikol disguises himself as David in order to make Emily lose control of her amulet. Also, Firelight we also find out that the accident was caused by a person who meant to commit suicide but caused the crash instead.
David's last Appearance was in Firelight at a camping ground in Emily's memory. It seems that he will not appear in any other Amulet books, as his storyline has seemed to been finished off.
