You recently betrayed Luffy for Arlong but came back for one thing he wanted from you.Since you where close to him he wanted you to make a deal.A blood deal.He wanted you to agree that you would make it back from Arlong alive and to make sure you didn’t break it he wanted you to do a blood deal.You met him down at the docks by Arlong park while Nami,Zoro,Usopp and Sanji watched you two do the deal.His eyes lit up when he saw you after what felt like years still alive
