Honestly? I've been thinking for a while that the Soru Soru no Mi might actually allow you to influence others' behavior by inserting a specific soul piece into them. I mean, we know that homies can never go against the Soru Soru no Mi user's wishes, so maybe "demi-homies" have much greater difficulty resisting orders than regular people?

IDK, I don't really have any real proof, just a hunch. But it might explain some Linlin's behavior in the present compared to her old self. Carmel's powerful soul influenced Linlin upon being transferred to her.
