1) Can't stand getting stitches. In fact he'd go so far as to hide before being forced to if they were necessary. He hates them.
And always has to be forced to get them if needed. (Occasionally must be sedated).
If he does get them he has a habit of picking them out because it bothers him.

2) hides his scar because he's embarrassed, ashamed, and angry that it happened in the first place. Angry at the man who gave it to him, ashamed that he couldn't prevent it, and embarrassed because he thinks his siblings wouldn't have made such a mistake.

3) he hates hospitals or anything resembling one and downright refuses to go near one. No matter the seriousness of an injury. If he is consciously able to object and get away he will.

4) Chaos is the only healer/Medicine Man/Doctor/etc. that Nita can't fully refuse.

5) he is able to do limited magic. But can only use Geokinesis and make things explode....

6) he was one of the many Choctaws to refuse to be led in the Trail of Tears, leading to his injury, but stubbornly held on and only moved to present day Oklahoma when eventually (many years later) asked to lead and help them when someone came back looking for him. He somewhat begrudgingly agreed and finally left his homeland.

7) he fiddles around with the bear claw on his necklace when angry, embarrassed, in thought, distressed, or worried.

8) he has a secret hatred of himself and will purposefully get injured in battle.

9) he has insomnia and normally has to take medication to sleep.

10) he has merinthophobia. (The irrational fear of being bound or tied up.)
