Attack on Titan Chapter 131 had me thinking heavily on Armin’s relationship with Eren & It showed me Armin still understands Eren more than any other character in AoT. I also believe he saw Eren’s memories in paths
The subjects of ymir are connected by paths that all cross at a single coordinate, the founder, which Eren holds right now. They allow ymir’s subjects to experience shared memories at times & I think Armin experienced Eren’s memories of the freedom he felt/guilt he felt in 131
Eren’s whole dream of going outside the walls & seeing everything the world had to offer was given to him by Armin. They are connected heavily by this, and it makes sense that Armin’s dream he gave to Eren allowed them to experience the “freedom” moment together
There is no one else in the paths where Armin sees Eren, which makes me believe this chapter Eren was showing Armin the many things we saw him do & his memories from the past year. Armin seems shocked & doesn’t even realize Annie is speaking to him when he leaves paths
Armin understands the need to throw away one’s humanity to reach a goal & also knows the people who can’t make these choices will never be able to change anything. This is important as it shows he can empathize with Eren’s decision and why he doesn’t think himself a good person
This convo Armin had with Annie this chapter mirrors the convo they had earlier in the series. Armin fully understands why Eren can’t be a good person to all people because no one can be. This doesn’t absolve the sin, but it also helps Armin empathize with Eren’s decision
Since Armin doesn’t view himself a good person, he always wishes to talk & understand people first before harsh decisions are made, sometimes to a fault. But this attitude is what helped him understand Eren & why he shares Eren’s mentality now
By the end of this chapter, Armin expresses the same sentiments Eren shared with Falco back in Marley. Armin now shares the mentality that hopefully the dream world they envisioned together as kids still lies beyond this hell that they were pushed into
After experiencing this view that Eren showed him, Armin now understands this sight Eren wished to see all started with him showing Eren this dream. I think Armin feels somewhat responsible for this & also why he still wants to see the dream come true, for Eren’s sake
