Who in the KS world would you pick to be your companion? Do you base it on who will help the best with a possible rescue and survival, or do you base it on the assumption that there will be no rescue at all and you need someone compatible for possible a long term relationship. Or do you pick someone in between -- someone who can help with a rescue but with whom you could also spend a lot of time together?
Or do you just pick your favorite girl and hope that you are never rescued?

I am curious who gets picked, and why.
