I keep imaging there being some kind of time portal and the ATLA group meets the new one from LOK. Even Lin thinks Toph is small ;_;
Hah, that's cute
Role reversal much?
Korra would probably screw around with her spiritual powers and accidentaly cause a rift in time, causing all te characters from the original series to be thrown forward into their time period!
Lin's face is just priceless!!!
