Well, it depends. I subscribe to the headcanon that the Wolfriders don't like strangers, especially not in the earlier years. Comes from the wolfblood, where instinct drives stranger wolves. Territorial.
Cone met Uli on what was supposed to be a very short lone hunt. She was very guarded, and did bristtle a bit of the plantshaper calling her wolfling and such, more because it gave imprssions of the most wolf like than actually offended.
The strangers on the other hand seem to notice that something is off, and that she is a little gloomy, but rarely push her. Then she met Beyond, who has the rare privelige of seeing her happy. (she was drunk on the apples Uli eats.) He gets away with more pushy and asking her to smile because he amuses her. (she doesn't admit it.)
Despite being guarded, she doesn't really have anything on the strangers she met, so they don't feel her sharp tongue as often. They usually think she is too serious and should smile more often.
Again, Beyond is the exception. When he does a joke he goes "I know you're laughing."
"No, I'm not."
*looks at her*
*tries to stiffle a smile*
Another thing is that these strangers seemingly acts with ease around her. After two-three years butting heads with most of her tribe and spreading sour moods, it comes as a welcome suprise. So she also tries to hold her tongue.
As for dancing, she won't join unless dragged into it.
Hope it made sense and clears things up.
