However, after Korra was incapacitated and nearly rendered powerless by an enemy Amon, leader of a subversive movement who specialized in taking away the bending abilities of people, she revealed to Tenzin her deep-seated fears of Amon, crying on Tenzin's shoulder. Tenzin offered her comfort and a higher level of trust was established between the two. Later when Republic City came under attack from Amon's forces, Tenzin, his wife and their children were ultimately captured by Amon and were facing the real prospect of losing their bending when they were rescued by Korra and Mako.
