-grins.-  Kindra has extensive experience with half-orcs, since I'll bet there are quite a few who end up on pirate ships.  So, she'd definitely not judge a half-orc by their tusks.  She'd be tickled by the idea of a half-orc knight and think it was serendipitous, the idea of a former priate turned 'good' rogue befriending a noble half-orc.
