Now...here's where things get tricky. In an effort to keep those who have bveen holding out to watch the last ten episodes of A:TLA on Nickelodeon, I've tried to keep spoilery content in it's own sections. Up until now, I haven't posted anything on Iroh.org from episodes that haven't aired on Nick. With my acquisition of the Book 3, Vol 3 DVD, all that has changed.


LINKS TO SPOILERY CONTENT ARE BELOW!
