In a fight before she dies, Max could be protecting someone she cares about deeply. As she takes the fatal blow, the look on her face as she realizes she can't be there for that person anymore would be extremely sad. And the person she was protecting would be left with a sense of guilt and loss.
Logan would be devastated. He had a deep connection with Max, and her death would leave a huge void in his life. He might become withdrawn, losing his motivation to fight for the causes they once shared.
