Meh, stranger things have happened in SW.
Dare I ask?
These two? Lovers.
Well, that’s what I get for asking.
I guess some EU writers were just really into inter-species relationships.
Somehow I think I just came across an even weirder one while reading the Lando series:

Apparently these two cat-men aliens are both clones and lovers. I’m not sure what to think about this one.
