The Last Of Us 2: 9 Details You Totally Missed From E3
4. Ellie Is Wearing Dina's Bracelet
In case you missed her name, the lady Ellie is kissing is called Dina.
Blink and you'll miss it, but there's some significance to the bracelet on both Dina and Ellie's wrists - it's the same one.
When the trailer cuts from Ellie dancing to Ellie killing, you can just make the bracelet out again in the darkness, on her right arm, identical to the one Dina is wearing earlier. Of course, this doesn't say outright that Dina dies, but if you think back to the first game, Joel wore the watch his daughter Sarah gave him 20 years on after her death. It was all he had left of his daughter.
One could assume that Ellie has the same idea with Dina's bracelet. Which means unfortunately, Dina's face won't be on the box, much like Tess. Dina's death could just be the catalyst for Ellie's apparent thirst for blood in this game.
Dina likely dies, so "I'm going to find, and I'm going to kill...every, last, one of them!" now makes more sense to us.
