I am too lazy to find the panel, but I really like the scene where Sanji asks Robin for help while he is captured by Black Maria. I know it's controversial because people use it to make fun of Sanj, but I think it is a great moment. Sanji trusts Robin and knows that she can fight Black Maria.
The whole interaction reminds me of Enies Lobby. I love how Sanji can be so encouraging to the Strawhats. Another favorite quote of mine is when Sanji tells Usopp that they need to rely on one another (I am paraphrasing). It is awesome to see Sanji finally taking his own advice because while he can't fight a woman, Robin sure can. He also has complete trust in Robin that she will be victorious.
