okay putting all this “losing the past lives connection was a necessary evil, etc.” discussion aside for a moment let’s look back to what korra’s gone through in the last two season finales:
she lost her bending (temporarily) in book 1.
she lost her connection to her past lives (permanently) in book 2.
so what the heck is she going to lose in the next two books?! ಠิ﹏ಠิ
