This forum has such bad takes oh my god.
Sanji is gonna save Chopper soon now that hes being double teamed. (MOST LIKELY IN ACT 4)
With Sanji saving chopper he could fight Pero and Wueen at the same time which is cool for you guys. This helps transition Chopper back to his role as a doctor to save Zoro, healing Zoro back leads to Rooftop Zoro again or King to Kaido.
