There’s a Beifong family gathering. Somehow Lin and Toph end up sitting at a table. Alone. They’re silent.
Opal walks over, holding Bolin’s hand. They’re talking, leading the conversation, when Opal just casually mentions Grandpa Sokka.
And Lin is like ARE YOU FUCKING KIDDING ME?!?! I GET SOME GUY NAMED KANTO AND THEY GET GRANDPA FUCKING SOKKA WITH HIS MAIN CHARACTER STATUS AND HIS FREAKIN BOOMERANG?!!!
(Toph’s basically does this in response: ¯\_(ツ)_/¯ ).
