Last Of Us 2: 25 Easter Eggs, Details & References You Need To See
25. Ellie Calls Joel A Dinosaur
You'd probably blink and miss this one, unless you remember everything about the first game.
During the section in the museum, where Joel and Ellie and are among the dinosaur skeletons, Ellie will pretend to answer the phone. When Joel questions what she's up to, she'll say 'Oh wait... one of the dinosaurs is here.' and make various quips about Joel being old.
It's believed that this is a direct reference to Joel's dead daughter Sarah, who during the first game sent Joel a very specific birthday card. This card, which featured a dinosaur on the front, said 'Congratulations' on the front and inside said 'You're not a fossil! (yet).'
It's very likely that this dialogue between Ellie and Joel is designed to show her their relationship mirrors that of Joel with his daughter, Sarah. It also has further parallels to that scene, as it's about Sarah giving Joel a present for his birthday - in Part 2, Joel takes Ellie to the museum as a gift instead.
