Mikasa and Armin are in the lunch hall, talking about what's going to happen to Eren, Armin fills her in on the court case over him and is shocked, they are then called to come to the court house to be witnesses. Eren is retrieved from his cell by two scouts (seen earlier in the series called Zoë and Mike). They lead Eren to some doors, shutting them behind him, he finds himself in the court room and is brought to the trial stand and shackled into place.
The Premier asks the MPs and the Scouts for their proposals on what to do with Eren, the MPs want Eren dead and the Scouts want to use Eren. At this point we are introduced to the wall cult. A large debate follows about Eren and if he is safe. Eren is listening to the debate and flips out, screaming and shouting at the court house, calling most of the MPS and civilians cowards. Eren is then kicked in the face by Levi, who continues to beat Eren, having knocked out his tooth.
The Commander of the Scouts makes a proposal to take Eren beyond the wall to see if he can be used or if he is dangerous. Levi backs this by saying he can deal with Eren if he is not safe. The premier agrees to this proposal and Eren joins the scouts. We then join Eren in a room with the other scouts who are talking to him and explaining what and why they did what they did, Zoë had picked Eren's tooth up and wants to look in his mouth finding that his tooth had grown back.
We join the scouts, heading to the old scout HQ, at the start of episode 15. After arriving at the HQ, Eren sees four scouts and names them: Petra, Oluo, Gunther and Eld. The scouts are ordered to clean, dust and de-weed the old HQ
Commander Smith is seen drawing up a plan and is talking to mike about the new recruits that would be joining them. After what can only have seemed like a long day, Eren and the scouts are found drinking tea. When they ask Eren how he changes, Eren tells them that he doesn't know how, just that when he bites his hand he changes.
Zoë joins the group a bit later and ends up discussing all her experiments she is doing on the two captured Titans. This lasts all night, until a solider comes in and informs Zoë that the two Titans have been killed. With a crowd around the vaporised corpses, Commander Smith comes up behind Eren and whispers questions in his ear "What is it you think you see? Who do you think the real enemy is here?"
Episode 16 begins with an equipment check for the recruits to see if the killer of the two Titans can be found, after a conversation between the cadets, we see a flash-back to where the cadets are watching the bodies of their comrades burn.
The cadets have to choose which regiment they wish to join. Jean makes the decision to join the scouts, shortly followed by Armin. Commander Smith addresses the cadets and tries to tell them why they should join the scouts.
After giving his speech, commander smith tells the cadets to leave if they dont want to join the scouts, lots of cadets leave but the cadets that remain are Mikasa, Armin, Jean, Sasha, Ymir, Historia, Connie, Reiner, Bertolt and a few others we dont know the names of.
The cadets are shipped out and training begins straight away, due to the upcoming mission. Eren is talking with the other scouts about the questions the commander asked him and the others in the previous episode.
Eren spots Mikasa and Armin and the others, and asks if he can go see them, he runs over and talks to them, finding out about the death of Marco.
The cadets new uniform arrive and they put them on, officially becoming scouts. We then find Eren and the others chatting in a barn and Jean asks Eren to prove to them why he's worth dying for, the scouts are then seen starting there mission.
