Our Sextape
I don't know if anyone has pointed this out yet, but look at this:
Lin, Katara, Kya, and GranGran all have the same notch in their hair.
It may be coincidence, but I just thought I'd share my observation. o:
It seems to be a watertribe thing, so it'd make sense if Lin had it because Sokka is her dad.
Not to mention their hair...Lin's hair reminds me of Katara's mom. And Katara's hair reminds me of Katara's grandma's hair...
Generational gap hairstyles?
Like, Grangran -- Katara's mom -- Katara -- Lin (if Lin is Sokka's daughter)
Gran gran --&Katara
Katara's mom --& Possibly Sokka's daughter Lin
Katara --& If Lin had a daughter...
