And also, the article says this episode featured 3 generations of Beifonge were brought together in this episode. Toph was with Lin and Suyin in the flashbacks, and Lin and Suyin were with Suyin's daughters, but at no point where three generations of Beifongs brought together.

Not a lot of discussion of the B-plot, Tenzin and his siblings looking for Ikki. Only a few bullet points, with no mention in the main body of the review. I thought that story did a fair amount of character development with those three characters and tells us a lot about their history.
