"There's no fighting"
Yes they were lol
Both attacked Luffy and he dodged them and landed hits on them
They got embarrassed
Lucci, Doffy, KIZARU,...GOT SAVED BY PLOT when losing
While Luffy still had Kizaru in a hold (only thanks to Kizaru not focusing on Luffy)
So yes, this is an extremely situational thing. There's no 2v1 going on here. Marco vs King and Queen was actually a 2v1 and even that ended up badly for Marco.
This is just Luffy grabbing Kizaru when he wasnt looking, and then sidelining him while the plot moves forward. Your guess is as good as mine for what happens next. I'm only here to speak on what already occurred.
