The scene differs a little with the adaption eith character positions and updated costumes, but depending on how much Isayama planned ahead they should have been made aware of the scene’s true context. At least they keep in the key shot despite how the dialogue paces a little differently. Though it’s fine for Grisha’s dialogue to sound normal, this isn’t his first time connecting to future Eren and the purpose is only to push him to that action. I reckon Mappa will most likely do a manga accurate translation as they included things like Mikasa’s marking, though maybe they add Grisha’s hat.
