My thought is I don’t think Sanji will break off from Luffy and Jinbe just for that; he definitely won’t do it first.
He may hit queen fast and throw him to the ground in front of people declaring his name as “Black Leg” Sanji in front of everyone but I don’t think he’ll break off and have a prolonged fight until Luffy is closer to the top.
I won’t be mad about Sanji vs Queen, but until we see the chapter and panels it’s too soon to tell the context.
