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.
