and OBUMMER gave the internet to the UN , which its primary members believe the same thing ! <| sep |> Tomatoa before acquiring his first shineys . <| sep |> I think it ' s useful to try and think about what this episode was about . I think strongly that this was kinda about the loss of self and selfsacrifice . Like if the city represents Buchan ' s personality , then the birds represent whatever forces of entropy that is destroying it . Some other significant seeming moments 1 . You have to crush their heads to destroy them maybe reflecting some incident where Bu ' s head was left intact while his body was destroyed ? 2 . The girls have to fit themselves literally into a tiny space within a robot to save ' what is precious ' 3 . The scientist demanding to know what Yayaka ' s motivation is before allowing her to use the robot 4 . The bird motif seems new , also . Though Buchan is identified with a bird in the ending credits .
