Now that we got all the bawwing over the chapter done with. I am still trying to figure out how the ship plans to infilitrate through the second gate of justice… You think they will disguise themselves and make it seem like its just another Marine ship entering for the epic battle ahead? It would also allow them to blend in with the crowd to over look the execution... I mean you would think there would be plenty of spare uniforms of the Marines on a ship that size >.> and since direct contact with Marine Head Quarters was cut off, they shouldn't know they are coming just yet.
Another thought that crossed my mind (this isn't prediction or speculation, just a funny thought) what happens if Luffy shows up first and they think the ship is a surprise attack from Whitebeard? Can you just imagine Sengokus face when he sees Jimbei, Crocodile and Luffy on the ship after all the things that have happened thus far XD
