Eli is a very tough person. He proves his points and is his own person. Eli does what he thinks is right even if it isn't. Eli, like his dad, is a very smart person. He started taking college classes
at an early age. Eli was also kind of a follower. Once they entered the compound, Eli took a step up and became a leader. Eli also works out. Eli also takes care of himself. Unlike Eli, Rex may sleep for weeks at a time and then stay awake for weeks (Bodeen, 2008, p.84). Eli is a good kid and shows it through his actions.
Eli and Rex have very little in common. For one, they are related. They also fight for what they want. I think Eli did not inherit Rex's traits
