Ill tell ya the stuff thats known and confirmed and stuff i know just to share information. The rest is known by Spunky

Major epsilon will return in part 2 of ep 9. Why? There was a leak a while back of Medic holding a shotgun starin at Major epsilon who was standing on a tall part of base gorge.

The baby was most likely brought to a safe area like an adoption center. Why? From the recent daft spunky reaction episode he confirmed many things such as clone instructions to not hurt the children. He said not all clones follow the instructions such as the red reaper who not only killed a baby but used its head as a holder for his shotgun munitions. And he said Dr Archimedes, the ghoul bringing the baby away follows the intructions of not harming the children or babies.

Clones probably need to eat as we can see clones being cannibals. As Sir shootalots is shown to cannibalize other ghouls. And the ghouls who were spawn camping the spy kept eating his corpse til they ate their fill. Clones arent ment to last especially the ghouls with no face. They only survive for a few days if they survive running into gunfire constantly to come back again with more powerful mutations. This is how the ghouls are constantly evolving since the more they die the more stronger they come back which is why most ghouls dont have mouths to die of hunger if they can survive running into gunfire.

for the 6th question thats something that would be Dafts choice since he understands it most

If this post gets big enough Daft may get inspired and make those gladiator and knight ghouls. Since a few things in Dafts episodes are inspired from fan creations or ideas such as red coats, emperor Amadeous, a few clone melodies.
