Platinum is probably a magician and older than FL by like 10 years or so, giving me sus vibes in a bad way. Alexandrite is so-so but bit better than Platinum although both of them are still after the former Pink Diamond. Amethyst, she's so timid, clumsy but it also gave her own charm but there's still a chance that it's an act. Pearl have this onee-san kind of vibe for me, I think she can be friends or best friends with Garnet considering their enjoyment when it comes to physical activities but she does gives me a mysterious vibe like she's observing everyone when she get a chance, especially the kitchen happening few chapters back. Garnet is actually an interesting character, i kinda hope for him and amethyst to go with each other because their chemistry click, amethyst is timid and clumsy and Garnet is there to look after her. And obsidian I have no words about her
This will be my guess... The 1st timeline ML probably under the Duke's order/shackles since the FL half sister basically said that the 1st timeline ML works along with jackass "father" for treason against the king and they finally finished, the Duke allows the ML to do whatever he wants to FL and that's probably why the 1st timeline ML was on verge of tears when he saw the FL leaving and FL didn't know this, she's used to being ignored by him and that's why she can't accept that he actually cares for her to the point that he kept her 1st timeline dress in his room before she regressed. I think he genuinely loves her, he just wants to finish everything he needs before settling down with her in the 1st timeline
Again this is just my guess
