He obviously has something in mind otherwise Kuma going back to the Holy land is just retarded. Bonney is supposed to find out the truth about him but S-Bear is definitely putting a death flag on the real Kuma. S-Bear might absorb his memories but the real Kuma's body is done for.
Iwas discussing it with someone earlier this week, and I said I think this might have been Vegapunk and Kumas plan all along. Discard the old Kumas body, and make it seem to the WG that he is dead, and then place his memories into the cloned Kuma, and essentially resurrect how him. This is the soul experiment Vegapunk had in mind.
Remember the arc Kuma was introduced him featured Brooks back story, where he was killed, but his soul returned to his body via a Devil Fruit.
What if Kumas memories get placed into S-Bear, and when his original body is killed, his soul returns to S-Bear?
