Thank goodness that Aang is able to recognize Isabela right away. This should make his eventual escape from the Mirror World a little easier on both parties on the two sides of the mirror. Hoping that he could hear her, she tries to hit on the mirror with her hands as she calls out to him.

“Aang, can you hear me over there? It’s me, Isabela. Don’t panic: I’m going to try to help you escape from the mirror world.”
