This is a sequel to the fanfic The Son of Salazar, which is originally by AlexisJames92 and also written by AlexHolster on Wattpad.
In this one, Sammael goes back to his original time in the future and in his 5 year old body. He never forgets who looked after him for so many years and also his familiars. He is never forgotten in history to be Salazar's adopted son and is even taught in A History of Magic. Helena Ravenclaw recognises him and realises that he didn't die. He is still sorted into Griffindor, but doesn't hold the Griffindor grudge for the Slytherin's, realising that they only act like this because they miss Salazar, and he did die from Mundanes, or Muggles.
