DO NOT READ IF YOU HAVE NOT WATCHED "THE HEADBAND"

At the end of "The headband" when [spoiler] aang escapes and and earthbends the exit shut, the only reaction from the other student is a :o face. [/spoiler] But i think there should have been a bit more of a reaction. I mean come on! he [spoiler] eathbended right in front of them! [/spoiler] dont you think that the student will/would report this? but the episode does not elaborate, and there is no mention of it. well that's weird.
