Mostly in a wife I'm looking for someone that we can ultimately work with closely rather than try to have to sneak around to do our thing. The imperials worry me a lot for this reason - without meeting them we can't know how hardline they are, and we can stumble right into having to hide in our own bedchambers. With the druids we don't have to worry about that, Haila being a noted shapeshifter means at least some notable magical capability, and the turning into a fucking gator would be very useful for protecting us in a close combat scenario - note that this is our greatest weakness in combat, if someone rushes us down we don't really have a great natural protection. Between her and Allana, she probably doesn't have Allana's baggage, and she's noted to be cunning and ambitious - if we meet her and this doesn't turn out to be a problem, it's a distinct plus, because so are we, and having someone to plot and plan with who will also keep us from being ganked in the fucking face is a GREAT thing in a spouse. Allana isn't an awful candidate either, among the druids.
Marion could help alleviate pressure among the imperials, but without meeting her we don't actually know if she is or is not an obstacle herself. I DO NOT WANT TO RUSH INTO MARRIAGE WITH AN IMPERIAL - or with anyone, really. I want to be able to entrust our spouse with a lot rather than just sort of try to avoid them like a character in a bad joke, so meeting them and getting a sense of how trustworthy and how orthodox they are is VITAL.
