John walked by Maggie saying "Bang! Bang! Bang!"
Maggie asked what he was shooting at. I couldn't quite catch more of his answer than "Blah blah blah blah," but Maggie apparently understood and clarified his response, "Oh, you were attacking the bad guys that were invading my room?"
"Yeah!" was John's enthusiastic confirmation of this. Maggie responded in an earnest (if sappy voice), "I love you so much. You are a good little brother. No matter what happens, I love you."
