Since the Town Council is returning on Legacies, it wouldn’t be a complete without the Fell Family. I saw a rumor/theory on Instagram saying that the new brother sister duo are the children of the new sheriff, and that they’re apart of the Fell Family.
If that’s true then she and everyone else on the Town Council will know about supernaturals in Mystic Falls. Just like season 1 of TVD when they knew, and target the Salvatore school since the Salvatore brothers had a history in killing the Fell family members. This is just a season 2 theory.
