Theory: Seraphim Kuma and OG Kuma have their brains connected, like Vegapunk.
CP0 starts talking about how they're going to kill Bonney in from of Seraphim Kuma:
Right after, OG Kuma goes sprinting away.
We know Vegapunk programmed Kuma to do certain things.
I bet Kuma made Vegapunk program him so, that if Bonney was ever in danger, Kuma would save her.
Seraphim Kuma sent OG Kuma a message saying Bonney's in danger: OG Kuma will show up to save the day at some point.
