Given Damon returned to life as a human, Julie Plec has said she would have to “give thought” to how Stephanie might factor into the plot of the Salvatore School.
The comparison is interesting, because Ian Somerhalder’s Damon Salvatore does exist in the Legacies universe, so this new character would, in fact be Damon 2.0.
We know that Damon and Elena had children and in particular a daughter Stephanie who has been mentioned on Legacies.
