2010
Lucas was among the civilians evacuated from Happy Harbor during Mister Twister's rampage. He smiled when he saw what looked like Red Tornado arriving to take down the villain.

Mister Carr broke up what could have become a fight between Conner Kent and Mal Duncan. Later in class, he discussed the current political state of Rhelasia. He was impressed by the knowledge Conner Kent displayed of the nation's history, as well as his question as to why it was divided.

During the Team's "alien invasion" training scenario, Carr, along with the rest of the students and faculty hid below the school's underground bunker and watched the Team's speech about how they would win and build from what they've lost, after the Justice League had been killed.

Carr went to the school's Halloween party wearing only an eyepatch.
