I guess you all did forget. Eren is Reiner and Reiner is Eren....

Hajime wanted the readers to deduce this after Reiner's flashbacks. Reiner was once a kid who wanted to take on the world but was always the last of his companions. He came out on top because of Marcel's hollygagging. Then when Marcel died, Reiner became the true soldier/warrior.

Then he met Eren. Eren also wanted to take on the world. Reiner wanted to kill all wall people, while Eren wanted to kill all titans. When Eren was failing, Reiner saw himself in Eren. He inspired Eren by being a big brother to him, always telling him the right thing to do, to always push forward, no matter what, as Kruger and Grisha always told Eren. The betrayal was probably the hardest thing Reiner did in his whole life. He still regrets, that if he had to betray and become Eren's enemy eventually, why befriend him? Why make him feel so angry and shocked? Why be his brother in arm, if eventually he had to try and capture him, and give him to Marley for the power to be passed on?

Reiner and Eren are the truest frenemies, and we won't see another fight, they've both become mature. It's been 9 years since Carla died. Eren knows the conditions that the Eldians and Reiner lived in, and what they were taught. Eren knows Reiner had no other choice...

They will just talk, or Reiner will lose his nerve and will probably faint when he hears that Bertholdt is dead. Eren will maintain his composure, similar to Eren Kruger.

My prediction: at the end of the 99th chapter, when Eren and Reiner have had that conversation, Annie will appear from behind (Salty!). The Tybur announcement will be shown most likely in the 100th chapter.
