In the raw version, Sanji’s line here is 「帰りたい」(kaeritai = I want to go back). What’s noteworthy is that he didn’t say 「帰りてえ」(kaeriteh), which is the same in meaning but is a more masculine way of saying it. My guess is that Oda purposefully changed Sanji’s usual gruff way of speaking so that he could deliver how desperately he wants to go home (“tai” means “want” after all).
That being said, when asked to speak up his true mind, Sanji only said he wants to go back, not that he wants help. He didn’t even think for once about getting assistance from his nakama, just that he’d like to go back :’( I really hope Luffy manages to convince him that it’s okay to get help, that he more than deserves all the love and support from the crew he endears so much.
