Halfway through the episode and listening to the Tower of Babel reminded me of something I heard recently but don’t remember where. After the recent solar activity someone mentioned the idea to build a giant cable into space that would be used to earth Earth. Perhaps this is what they were trying to build with the tower!?

Another brilliant episode - brave mood taking on the Avatar the Last airbender fanbase. Whilst not in the Avatar the last Airbender series in the sequel Legend of Korra an air bender called Zaheer using their air powers, he pulls the air out of a victim's lungs, causing them to suffocate.
