Character traits in “Pax”

In the book Pax by Sara Pennypacker, a character named Vola is a complex person, with both a caring and a tough side. She shows her caring side when she takes in a boy named Peter who broke his ankle. Vola takes care of Peter until his leg is healed. On her tough she she wants to know everything about Peter and she threatens Peter to talk. Also Vola is like a mother to Peter. Evidence to support this theory is that Vola made crutches and fed him food. I think that Vola is also really suspicious because she wants to know why Peter just wandered on to Vola’s property. Overall, I think Vola has a motherly side to her and a tough side.
