Last time we see Drake in Manga - not down. Anime says differently - conflict with manga present.
Last time we see Peji-Wann in manga - not down. Anime supports the same, there is no conflict.
- The Manga also supports the notion that we dont know what happened afterwards.
Do you know what off-panelled means ? It means something happened....but Oda didnt show it. Saying that Drake and P1 was concious when they was last onpanel, as an argument contradicts the fact that something can happen offpanel. Now going by your logic, Sanji ran away in both instances since the last time we saw them they were conconcious. That is illogical reasoning, because Sanji running away based on that specific panel of P1 still being concious is actually contradicting what Oda has shown us. Which is Sanji is superior to P1....
Not only is he shown superior, we also have much more proof that he was knocked down. As in he kept quiet for 2 weeks, he never appeared for 50 chapters, he wasnt a threat to Sanji anymore, Drake is pissed at Sanji for a reason.
Now if we look at your illogical proof vs what is shown. Then we have this.
For Sanji running away: Not a contradiction because P1 was last seen unconcious. Yes unconcious and....the inferior fighter
Against Sanji running away and For Sanji defeating him: Sanji is the superior fighter, he kept quiet and irrelevant for 2 weeks, he never appeared for 50 chapters, he wasnt a threat to Sanji anymore, Drake is pissed at Sanji for a reason. Also Sanji seems him as a weakling that Usopp can protect Nami from
Verdict it is more logical and better to believe that Sanji defeated him and also deems him no threat. To the point he believes Usopp can protect Nami from him
As for Drake I agree, there is no proof that Sanji defeated him. But their is also no proof of what actually happened. Saying that Drake was concious when he was last onpanel, contradicts the fact that something can happen offpanel. It also fuels the argument that the plotline magically superceded and ended with Sanji and Drake teleporting in different areas. Honestly thats the best way explanation of what could have happened based on your reason.
Verdict: Who knows what happened.
