I Have a Theroy That Ellie Is Getting Revenge For The Towns People Because Neil Druckman Said "How Far Would You Go To Get To Justice For Those You Care About" I Think He Is Referring To A Handful Of People Who Might But Also I Have Another Theroy About One Of Those People Die I Think Joel Had A Kid In Those 5 Years And Maybe Ellie Had So Much Hatred Because Maybe She Looked After Joel's Kid As A Sister And That's Why She Is Getting Revenge Plus Tommy Said "We All Have To Wrangled Up At Some Point" I Think Joel Sort Of Did Wrangled Up With Someone And Kid Came From It.. I Feel This Way As Naughty Dog Has History Of Misleading Us Through Trailers..
