<P> In the epilogue to Deathly Hallows, set nineteen years after Harry defeats Voldemort, Harry has named his second - born son Albus Severus, after Albus Dumbledore and Severus Snape . As Albus is about to enter his first year at Hogwarts, he expresses concern that he will be sorted into Slytherin . Harry tells his son, "you were named for two headmasters of Hogwarts . One of them (Snape) was a Slytherin and he was probably the bravest man I ever knew ." </P> <P> When Draco and Astoria Greengrass' son Scorpius Malfoy finds himself in an alternate timeline in which Voldemort won the Battle of Hogwarts, killed Harry and his allies and instituted a terrible reign of terror, he desperately searches for help in restoring history to its original course . He finds that in this reality Snape is still alive and still teaches at Hogwarts, and asks for his help . At first Snape is suspicious of him, since this timeline's version of Scorpius is a bully and a Voldemort stalwart . But when Scorpius shows that he knows of Snape having been in love with Lily, Harry's mother--Snape's most closely guarded secret--Snape becomes convinced that he does indeed come from a different timeline where Harry and his friends won . Snape then reveals that he, together with the fugitive Ron and Hermione Granger, maintain the last remnants of Dumbledore's Army--still waging hopeless resistance against the all - powerful Voldemort . In talking with Scorpius, Snape had learned that Harry would name his son "Albus Severus" and would regard Snape as "probably the bravest man I ever knew"--and is deeply moved . Though having guessed that in the other timeline he would die, Snape nevertheless willingly helps Scorpius recreate this timeline--and being discovered by Dementors, Snape sacrifices himself in order to cover Scorpius' escape . </P> <P> Severus Snape appears in all eight Harry Potter films, portrayed by British actor Alan Rickman . Rickman was Rowling's personal choice to portray the character . He had conversations with Rowling about his character and is one of the few Harry Potter actors that she spoke to prior to the completion of the book series about the future direction of the character . "He knew very early on that he'd been in love with Lily," said Rowling . "He needed to understand (...) where this bitterness towards this boy who's the living example of her preference for another man came from ." </P> <P> Rickman used this knowledge of Snape's ultimate loyalties throughout the films to decide how to play certain scenes, deliver specific lines, or use body language to convey specific emotions . When the directors of the films would ask him why he was doing a scene a certain way or delivering a line in a specific manner, Rickman would simply reply that he knew something they didn't . </P>
