Fruity men

Anya and him are relatively close, not besties or anything but she knows quite about his struggles and watches with him that he takes his pills properly and helps him with his T-shots generally

Jeremiah definitely struggles sometimes with Daisuke as he doesn't know quite what to do all the time, and while Daisuke doesn't know the depths of his situation necessarily, he can help him quite good if he's freaking a bit and just needs to be brought down.

Swansea and Jerry have a very unspoken but mutual respect. It's not to the full length of his relationship with Daisuke, but sometimes he might give him the littlest of pep talks.

The captain, pre crash, would have been generally supporting of Jeremiah, though they never got particularly close or anything. It's not like neither of them dislike the other but they are quite on a different wave length which causes some tensions here n there.

Post crash Jeremiah barely acknowledges Curly's different state, almost being too casual about the whole thing. Does it freak him a bit? Kinda, but he goes into more of a fuction mode with this and does some semi healthy radical acceptance.

Jimmy

While he doesn't know everything that's going on with Jeremiah, let alone any detailed diagnosis, he catches whim of his general possibility to be instable and begins to be extremely paranoid about him. Jimmy will probably start telling the others not to trust a lunatic like that guy who 'has to take pills just to not get violent' (probably a phrasing he'd use)

Jimmy ends up talking himself far enough into not trusting him that he finally decides to take his pills from him to show the others his 'true colors'.
