Rex/Ventress for that ship meme!
Put a ship in my ask and I will tell you a bit about how each of the following scenarios would go down for them:
Fake dating I think the best way for this to go down is that the two of them run into each other while on unrelated undercover missions at the same event. They are very Not Subtle about noticing and recognizing each other, and people can tell, and they stumble their way into claiming they're a couple when trying to explain. They have to run with it, which involves getting in each others' way a lot because their respective missions aren't actually compatible.
Bodyswap A primary conflict here would be "Ventress no longer has access to the Force, and thus feels as though she's lost an entire sense, and is kind of freaking out about it" and "Rex now has the Force, and is wearing a body that is addicted to the dark side, and he has precisely zero experience in controlling it." They're stuck trying to find/relocate the other person in order to switch back, and the whole situation is Not Helped by the Force situation.
Sexpollen/fuck or die/aliens made them do it Eeeeeeeeh classic plot format, captured by Zygerrian Slavers who want them To Breed to see if they can get some Strong And Durable babies out of these new holdings.
Dark!fic [buries face in hands] Ventress (threatens to) torture Rex for information. He's unwillingly and unreasonably into it. Things spiral, and it gets worse before it gets better.
Secret kinks I think Ventress wants Rex to tie her up. I have malleable headcanons as far as kink goes for most characters, including Ventress, but with Rex, I think she's a bondage bottom.
Their first kiss Definitely a rough and bloody and "covered in ash and dirt" mid-battle sort of thing.
Meeting the parents [stares at keyboard] I think the closest thing either of them has left to a parent is Dooku? Jango and Ky are dead, and Ventress doesn't know really know her bio mom or Talzin, so uh. I guess. I guess Rex has to beg Obi-Wan for lessons on The Right Spoons For The Eight Course Meal so he can go meet Ventress's grump grandpa in a setting that isn't attempted murder.
Moving in together I am not convinced either of them knows how to go about finding an apartment. They've both lived either With An Adult or In Military Housing for most of their lives. I mean, Ventress probably did something between leaving Ratattak and finding Dooku, but I doubt it was legally signing a lease, you know? I think they move into a wing of Dooku's castle for about five weeks before they're looking for a way out and move to Coruscant or something and just temporarily end up in a Jedi Temple apartment while searching for housing because living with Dooku is suffocating, even with an entire castle to avoid each other in.
A crossover of my choice Okay I know this is a little stupid but please imagine them dressed up as MCU Hawkeye and Black Widow thank you
An au of my choice Some kind of fairy tale AU where Rex is a brave knight in shining armor and Ventress is the Intimidating Witch that he needs to confront and defeat in order to Gain A Useful Object for whatever fairy tale plot he's following, but he somehow ends up dating the witch by the end? She's not a good witch yet, but she's not attempting murder, so it's fine.
