User blog comment:Fire Eater/Differences between the manga and the anime?/@comment-1327106-20180628050428

The three I can think of off-hand that resulted in additional/different scenes are in the Female Titan arc In the anime, the special target restraining weapon is used on Annie twice; once in the forest, and once in Stohess District. The Stohess District use was anime-only and presumably was to pad out the episode.

Similarly, the return to Karanes/Calaneth district is amped up in the anime. In the manga they just go back. No fuss. But the anime adds the original characters Jurgen and Dieter who go back for their dead friends and end up bringing a horde of Titans down on everyone else. All of that fight, Levi tossing Petra's body, and given her emblem to Dieter was anime-only.

Lastly, the anime ramped up the theatrics between Erwin and Nile when Annie transforms in Stohess. The anime had Nile being strongly suspicious of Erwin and not wanting to let him go, to the point he aims his rifle at him and Erwin goes through this long list of things Nile should do if he's going to take over his operation. In the manga Nile immediately realizes that everything happening is Erwin's plan and the manga leaves it at that. The whole exchange is just a few panels. (I dislike this particular embellishment because it makes Nile come off as more of a dick than he actually is, given the later history we get between the two.)
