Sanjis line about forgiving a woman's lies is one of the best when you know the context
Robin was lying to protect the crew, she didn't wanted them to get involved, so at that moment Sanji knew she was lying, he forgives her lies and goes to help her, which leads to all the Sea Train stuff
Not surprisingly he says "A man needs to know when to forgive a woman's lies"
You're not making yourself a fool, but the opposite, and that makes a lot of sense
Sanji's mindset is always ahead of everyone else
What doesn't make sense is Zoro calling himself the King of Hell out of nowhere and then go to sleep, and scream in fear due to grim reaper, like... Aren't you the amazing King of Hell? Does that even mean something? Where are your balls at dude?? Do something
For Robin its the same, makes no sense at all, it feels like she took that line from an Emo band fanpage on Facebook in 2010. But it fits her epiteth, so its debatable
