10 Most Emotional Avatar The Last Airbender Moments

10. Sokka Admits he Doesn't Remember his Mother

The episode The Chase in Season 2 establishes a clear contrast between Toph and Katara. The two operate on entirely different levels, so it makes sense for them to clash. This relationship is further examined in Season 3's The Runaway. After almost an entire episode of dispute between the two, there is a blowup and Toph storms off.

This is where the emotional moment appears, as Sokka attempts to comfort Toph. He discusses and addresses Katara's mothering, and claims that he can't even remember his mother, and he has always seen Katara as the person who cares for him.

This dialogue is heart-wrenching, as although it was always clear that Katara was the matriarch of the group, we come to realise that it's a manifestation of the impact that losing her mother had on her. She cares so much for others that she takes on the strenuous task of caring for everyone, because she knows how important it is that they have someone like that in their lives.

This sequence is only made better when we discover that Katara heard the entire conversation. It's used to strengthen the bond between Sokka and herself, and put an end to the petty squabbles with Toph.
