So supposedly Vegeta trained with Yardrats to learn a technique which allows him to release the energy gathered by other warriors when they absorb it from another source like a planet or a fusion. But now Moro is fused with 73 and apparently Vegeta can't use that technique on him even though he can't fuse with Goku because Moro/73 fusion who absorbed his powers now can use the power to defuse him on him. How does this make sense? What did I miss?
Why Vegeta can't defuse Moro/73 fusion?
