In short:
-Guts and Casca have sex
-Casca's pregnant at the time of the Eclipse, and is subsequently raped by Femto, tainting the child
-the demon baby is born shortly after the Eclipse
-Femto uses the demon baby to incarnate himself into the physical world, hence the Griffith we know now
-here's the tricky part. The demon baby either split itself into Griffith and the Moonlight boy, or Griffith and the boy are one. I'm personally going with the latter.
Unless the boy isn't related to anyone, but that really wouldn't make any sense.
In other news, Berserk's already going on break after this chapter. WTF, Miura. Not even 3 chapters this time around?
There's no proof that is Griffith and Caska's child, but is the higher possibility. It also could be Guts and Caska, but I think the possibility is quite lower. Let's wait and see.
I thought that even this new chapter was to show Guts condition. I think this mermaids part is being quite long, even so, it showed some progress.
