1.father said don't give into death, and endure the pain/suffering and nika will save him. kuma has honored his father wishes.
2. bonney showing to blessing/light in kuma darkness. and she been trying to save her father. she main driving force which is gonna get luffy motiavted more to save kuma and her!
3. his body is on instinct to save bonney as shown present time, not fully walking corps
4. vega punk told luffy to bring bonney up stairs, where he later told bonney to restore kuma it would only hurt her... it did.. so vega punk must done restore point but needed bonney or he wouldn't led her to kuma room with the copy memory
5. kuma memory are able to be restored thx to either pudding or soul/memory theory vega punk wonder about, or s bear.
6. Saturn needs to die so kuma can be freed, people saying kuma gonna explode is not gonna work. and i don't see luffy letting kuma become a pedro point 2, in explode death, plus saturn shown to heal.
