Griffith?! What the fuck?! Why would Griffith be in the child of moonlight's body? Was this Griffith's way of trying to relive the time when all three of them were together? Are there actually two Griffith's? Like, Femto is evil Griffith, and the child of moonlight is the good Griffith that has actually been watching over Guts and Casca all this time? Oh, man. My mind is racing.
Thank you, Miura-sensei, for everything you put into this incredible work of art...
Guts & Casca's child became Griffith's host body during the Incarnation Ceremony in Albion. However, Griffith didn't take over the body entirely, traces of the Child remained. It is he who watched over Guts & Casca, his parents, on nights of full moon. Here's a picture side-by-side for the Demon Child maturing into Griffith's host body in chapter 171 and the child reverting into Griffith at the end of chapter 364.

If you want to be even more mind blown, Guts & Casca's child was in Chapter 1 inside the Snake Baron's jail watching over Guts. What are the odds that he ended up reunited with his parents for the final chapter? A chapter that is not the End but happened to be the last we'd get. There's something poetic about the whole affair.
