Rihal Min finds Yani holding Marco's equipment and suspects that there is something wrong with her. This is also the place where the whole animation is most worthy of thinking and deliberation. Let me explain it to you briefly.
1. Ermin suspects Yani, but actually there are some evidences or doubts.
(1) holds Kyle's equipment, and Armin knows that there are traces peculiar to Kyle.
(2) Two captured giants in the barracks were killed inexplicably.
(3) When the Giantess first appeared, Elming shouted a puzzling sentence: Could the guy who was in a hurry to die have already taken his lunch? The giant stopped at once. The phrase "dying guy" is similar to "slang". Only the recruits who participated in the 104 recruit training knew that this was the time of the canteen accident, and it was naturally Allen. The giant woman responded to this and proved to be one of her own.
He was caught by a giant in Ermin, but the giant took off his hat and looked at him. He let him go without killing anyone. This not only proves that the giant has personal consciousness, but also knows him. I even knew him well and recognized him at a glance.
(5) Lena was firmly grasped by the giant and finally escaped easily. (Of course, I thought Lena NB hadn't read the back part of the comic. )
(6) This is Allen's discovery. When the giant was fighting, Allen finally recognized Yani's fighting posture and blurted out "Ah ...", but before she finished, she was shot in the head by the giant.
(7) The giant does not eat Allen directly, but runs with her mouth full, which shows that the giant knows the value and function of Allen. Elmin also analyzed it when he was investigating outside the wall. "In other words, there are giants among those who witnessed the transformation of Allen." .
The sixth point is Allen's observation. Li San, Zhang Bing and Allen have all directly fought against the giant, while Elmin, Joan and others have all had close contact with the giant.
2. In other words, Yani's problem is not only Emin's personal inference, but also a combination of opinions from many parties. Otherwise, if Yani is rounded up without a great degree of certainty or several contradictory evidences (the so-called isolated evidence can't prove this), the task will hardly fail, and the investigation team will make things worse. Allen and others estimate that there will be no future.
3. To sum up the above points, we can analyze them from the perspective of Elmin and others.
(1) The first is Kyle's equipment and killing two giants. After the death of two giants, the Corps suspected that there was a mole. But all the equipment was checked, and there was no trace of use. In other words, to kill a giant, you must have equipment other than yourself. Ordinary people don't have a second set of equipment. So Yani took Kyle's equipment. What's the purpose? There is a great suspicion here;
(2) Through 3 and 4, the Giantess is almost certain to be a freshman in 104 training camp. She is familiar with Allen and Emin and has witnessed everything so far. Ok, 104 is a newcomer, blonde, good at fighting, capable, female. I can't think of any other candidate except Yani.
(3) Of course, there was only one blonde in 104, and there was also a blonde goddess, but after the goddess entered the investigation team, she stayed with her teammates and had sufficient alibi. Only Yani, who entered the gendarmerie regiment, had enough time and space to commit crimes.
(4) As for what Allen personally observed, it was a direct plus. Needless to say, Allen's martial arts belongs to Professor Yani.
Therefore, after the investigation outside the wall, the existing evidence completely points to Yani. Even me, I'm afraid I would have more than 90% confidence to doubt Yani at that time. Besides, in the end, we didn't catch Yani directly, but lured Yani to the underground passage first, so that we had ample opportunities to prove ourselves to Yani (if it weren't for giants who don't have to be afraid of the dark, all other giants except Allen need sunlight as energy). And the underpass can limit the giant's action)
