I saw some "summaries" of the chapter, but they seemed like BS to me so I didn't post (or at the very least, very poorly translated). But from what I got, not a lot happens in this chapter.
The mission is successful and they capture Nick's killer (details on how is kind of confusing. I guess the people in the warehouse give the killer up, because they make a deal with Levi and the squad..or something). Anyways, they take the killer back to their hideout, and torture him to get info (the torture/him talking doesn't happen this chapter. It's about to happen).
Eren and Historia have a moment together, but it's a brief exchange. Both are sleeping in the hideout, and wake up and have convo. Eren makes a comment about how he didn't like who she was before (I guess implying that he likes her now? lol wut). And then SUPPOSEDLY, Erwin finds out that it's the King that had Nick killed, and is hellbent on getting Eren and Historia. That he won't stop until he gets them both. So Erwin says that they need to take out the king (this last part seems a little crazy, and I don't buy it. I guess we'll see). I guess they are torturing the killer to see who his informant was (they have a traitor in the army, since they knew where Nick was placed). (Fans are speculating it's Rico).
And then there is some other shit with the lady with black hair that Eren saw last chapter in his memory. Whoever was translating the summaries claimed she was Historias tutor, and has the ability to manipulate memory (there is a scene where she actually talks to a Titan...so I guess she's a coordinate?). < this last part is very confusing and muddled, and I'm not sure if it's actually real.
Like I said, I guess we'll know later tonight or tomorrow if any of it is accurate. I'm pretty sure some of it is (just based on the pictures we have). But you know, people like to troll all the time with summaries as the scans are coming out.
