Answer: Will give the stranger a nickel to alleviate her guilt
Explanation: Guilt is a known feeling in psychology that occurs after a mistake has been made that could harm others. This feeling is about the part of the personality that is about morality and ethics. Whether the mistake was made intentionally and also by accident, there is a sense of guilt. Such a feeling, in itself, is not bad as an incentive to correct the damage done, but it is not good to bear the burden of guilt for long, as it becomes anti-productive.
So Julia, in order to alleviate the guilt, will help some stranger on the bus, thus reducing the sense of burden, so that eventually she can smooth things out with her friend.
