varrick definitely isn’t sokka’s son because sokka’s genes could never produce such a vile offspring, but varrick definitely did have a poster of sokka in his room growing up, and a picture of sokka he carries around in a locket that he kisses for good luck (even though he knows sokka would look down on him for it because he famously loathes superstition—which is so cool of him actually), and every meeting varrick’s ever had with chief katara about how his innovations could improve the southern water tribe end with at least half an hour of him grilling her with questions about her brother. so it comes as no surprise that when katara receives an invitation to varrick’s wedding in republic city, she politely declines on the basis that she needs to wash her hair that day.
