Which best describes Marcus' tone in this excerpt from Little Brother?

Mom gave me a long hug, and I noticed how thin her arms had gotten, how saggy the skin on her neck was. I always thought of my mother as young, pale, rosy-cheeked and cheerful, peering shrewdly through her metal-rim glasses. Now she looked a little like an old woman. I had done that to her. The terrorists had done that to her. The Department of Homeland Security had done that to her.
