Does Brian know what goes on at the Green Lantern? On what evidence do you base your answer?

Brian was barely six, and no, he did not understand what happened in the Green Lantern.

"I asked her what goes on inside the Green Lantern," he said.
"Really?" I was impressed. "What did she say?"
"Nothing much," he said. "She told me that men came in and the women there were nice to them."
