One nice thing I discovered, is that the "loyal" personality doesn't necessarily mean they'll always agree with me, it just means they'll concede to my point of view. I've had a couple of instances where my AI partner will disagree/argue with me about a point, even though set to loyal. There was no RPS match to reconcile the differences, but they still existed. Frankly, I'm fine with that, though a subsequent playthrough will likely include testing the variant personality options.
