Flik/Odessa. Either an early mission for the Resistance, perhaps in which they get cut off from the rest of the group or had to act on their own from the start, or maybe an alternative in which (spoilertext) Odessa escapes the hideout when the Empire shows up. Action-y shenanigans--however absurd--to get out of it would be fantastic. I'd love it if they were already in a relationship and that made little appearances, but it's not necessary if you prefer not to do it. If you'd like to add any kind of blood/painplay or injury kink, I'd be A-OK with that.
