looks like he got a little...
aHEAD of himself.
Do to it what you did to Nike!
Well, it didn't kill him before eating him, so probably Saturno will wind up as part of a cluster of minds. Hopefully he'll be able to gain control somehow...
Actually, come to think of it, his core might not even be in his head, so he might be fine. Just sorta... headless. Like Alpha.
By now, he has a lot of cores http://demoneater.thecomicseries.com/comics/443 but his brain is still in one place (probably still in his head, near his original core).
