Fukurokuju's words might very well come true. "Capture one of them, no matter who it is, the torture will reveal us all their plans..." This scenario is highly likely to happen, someone among the pirate alliance will get captured and tortured. It would explain and show us what happened to Killer and possibly we could see other members of Kidd pirates in torture chambers. The question, like the title says - Who is going to get captured and tortured? It could be almost anyone aside from Luffy and those who aren't present in Flower Capital currently. There are few candidates who have the highest chances to get captured and those are the ones that were shown right after Fukurokuju said those words - Zoro, Sanji, Usopp and possibly Law. Zoro is already injured and with Kyoshiro there it's not an unthinkable scenario that he gets captured. He could possibly handle the torture the best among all candidates but still it would show it's horrors. It might have been foreshadowed even, back in Ebisu town, when people told him he should smile more, he might be fed a Smile fruit... However, he is currently saving Hiyori so it might also not be him. Usopp getting captured is something likely and theory about his capture already exists. He would be put to a test as a brave man of the seas. We all expect him to spill the beans fast and he even agreed in discussion with Nami but the opposite might happen. He is currently saving O-Toko so it also might not be him. Sanji is what looks to me the most likely candidate because he isnt saving anyone currently and while Usopp fled the scene with O-Toko it seems like Zoro is fleeing too with Hiyori while Sanji remains in the clash with X-Drake and gets worked up because he called him a Vinsmoke. I expect the torture to trigger whatever modifications that werent triggered when Judge did those experiments on his children. Another likely candidate could be Law. It seems like he is in a helpless situation considering that Hawkins has life links with his crew and Bepo's location is unknown... I expected him to get captured back then together with Luffy but it's not too late and Hawkins said he would be joining the prison soon. Not sure what to expect from Law's torture... What do you think?
