Spoilers, I guess? They're vague, and hardly up to date, but beware anyways!
I gotta say, Leia and Nasher would make for great additions to the datable roster. They'd make for some nice variety, and they both have good story potential. Obviously a story centered on Nasher would be rife with drama, considering what he contributed to in Runan's story, and as for Leia...
She alludes to some terrible event in her past that leads her to distrust humans. She's also been in a relationship before, one that didn't last. Earning her trust would be a feat and a half, and thinking about the feels that could be unpacked there has me really interested. Heck if I know if she'd even be eligible for a spot on the datable roster -- it's a bit presumptuous of me to assume that an expansion will ever be on the table, let alone that the only lady in the game would be allowed on it. But I thought I'd put my two cents on the table anyways.
