Auel: You. Ah. Debone fish... really nicely...
Neo: *SHAKES KIRA'S ARM* DID YOU HEAR THAT
Kira: I
Shinn: ... :I
This blog is canon in terms of the events in Gundam SEED and all the events in Gundam SEED Destiny up until Phase 42. It assumes that after Neo is given the Skygrasper fighter jet, he does not return to the Archangel and to Murrue Ramius. Rather, he left as he was told, seeking refuge during the remainder of the war until it was safe.
Currently, he still thinks of himself as Neo Roanoke and not as Mu La Flaga—he is, however, slowly receiving memories of his life as Mu, which constantly messes with the false memories that had been implanted into his brain by LOGOS.
