I don't know if confrontational is the right word but I like the way she speaks her mind and doesn't try to hide what she's feeling. For example, when Heidi was pissed off at Mikkayla for putting her in the HW house, Heidi pretended to be totally fine and happy but it was obvious that she was lying, whereas when Mikkayla saved herself, Tully said somethign about her choice being unfair for some reason. I don't agree with Tully but at least she's not too shy to say what she's thinking. And because of that trait, she has the potential to cause conflict in the house, which I think is a good thing because watching everyone get along gets old quickly.
