WHAT'S NEW IN THE LEAK — Perhaps the biggest surprise is the revelation that Ellie isn't the only protagonist of The Last of Us Part 2. The other playable character is Abby, a woman who was introduced during the Paris Games Week 2017 trailer. Very little was known about her previously, but these new leaks reveal that she's the daughter of the surgeon Joel killed towards the end in the first game during his mission to rescue Ellie. The switch to Abby's perspective happens about halfway through the sequel, according to a level list also included in the leaks.
This makes for a controversial choice considering the leaks also reveal that Abby kills Joel with a golf club. Jesse, another character who was featured in the E3 2018 trailer, is also confirmed to die at some point.
The story comes to a head as players fight Ellie and Dinah but play as Abby. This leak didn't make it clear whether or not Ellie dies, though some other leaks claim that she does. The cyclical nature of revenge is the very obvious theme connecting it all, exploring how it changes Ellie and Abby. Based on these leaks, it sure looks like Naughty Dog wants to comment on how revenge can make a villain out of anyone.
This makes for a surprising and subversive route for The Last of Us Part 2's story to take, and it's not one that sounds like fun to experience firsthand.
