Sonar's a complicated creature. As outwardly volatile and abrasive as he can be in both good and bad moods, few people know how to actually handle him when he's at his lowest points. It's quite a bit simpler than it seems: Keep showing the drake that you care, even when it seems like he's mere milliseconds away from biting your face off. He'll never cross that line. He just doesn't WANT to admit it, but he need this. He needs to hear that people still care about him beyond merely what he is. That who he is matters just as much if not more. Amidst everything, it's easy for him to forget that.

Just a little vent piece I made. I rarely ever feel these feelings, but Sonar sure as hell does. Just goes to show exactly why he is the way he is some times.
