The way Queen spoke was as if he was mad Sanji used the RS against King, but not him lol
The direction Oda is going with this is funny though.
It seems like he is playing with the conflictual part of Sanji towards his family, but it's clear at this point that he'd end up being unable to fight against his blood and thus ultimately use the RS to protect/fight what is to fight/protect at the decisive moment to help Luffy become the pirate king
