I love Nami and Usopp's friendship. Seeing them depend on each other and Nami confiding in him that they're the "weak" members of the crew, all while showing us in this arc that they aren't weak at all.

I'm actually really loving this arc because it gives the otherwise somewhat useless characters ( Usopp and Nami ) a strengthening arc. It's been over 100 episodes and they're finally launching themselves into the field of power that the rest of the Straw Hats are on. Nami's battle was cringey at first, but it's got me so excited to see how she'll use her quick wit and thinking to her own advantage now she has the proper means to defend herself against a worthy foe.
