Attack on Titan - 進撃の巨人, Shingeki no Kyojin.

Tbh I honestly didn’t know Zeke was with the scouts even after watching the episode. I found out when I watched a reaction video of the episode lmao  :pikachu:  

Edit - Reason being he had his joints cut off. 

I still don’t understand it either. I don’t get how Levi hasn’t killed Zeke after what he did to Erwin and what Levi promised he would do. Possibly the promise is still lingering at the back of his mind? And honestly I thought that soldier that was with Zeke (Helena) was Armin and I’m still struggling to see how and why she’s involved.

She does look a lot like Armin, I also mistook her for him lmao. But apparently, she's a follower of Zeke, so he probably talked her into the plan, the problem is that Pieck knows they are close as she had a "personal interest in her".
