Got a bit of a theory for you. I saw a comment on a video about the latest chapter and they make an interesting point. The scene with Reiner and the kids just before the train scene you see a person on the left of the scene with the armband thing on the wrong way and they have similar hair to Eren. They also mentioned none of their boats have arrived back from the scouting trips. What if one did and that one contained Eren and possibly Armin with the goal of infiltrating them to possibly kill Reiner and Zeke.

This is a long stretch but at the same time, it's a detail that was added which may be for aesthetic purposes or a hint to the infiltration theory. Potentially next chapter may be Eren and Armin if they are there transforming on the train and fighting the shifters.
