It's mostly seen at the end of the film in two scenes; first of all during the Pensieve scenes with Snape’s memories. This is the part where Snape’s love for Lily is revealed, but with one notable part: Dumbledore asks about Snape’s feelings towards Harry, and basically asks if his feelings towards the young man have changed. In response, Snape reveals his Patronus: a doe, just like Lily’s. Dumbledore asks “After all this time?”, and Snape replies “Always”.
When I saw this, Snape being Harry’s real father was the first thought to cross my mind, but I quickly rejected it because the movie still wasn’t over.
When the Voldemort section of Harry has died and taken Harry with it, Harry encounters the dead Dumbledore. Harry asks Dumbledore if it’s curious that Snape’s Patronus is the same as Lilys; Dumbledore says that the more he thinks about it, the less curious it is.
That’s not much to go on, I know, but the fact that Snape and Lily are so bonded that their Patronus is the same, and that Dumbledore knows the truth about it sparks a lot of thought.
This is all from the movie, but in the books James and Harry are said to have thin faces and untidy black hair sticking up at the back. Snape is also supposed to be thin and have a thin face, a hooked nose, and long black hair. It is also said that Harry looks a lot like James except his eyes, which are Lily’s, and his nose which is bigger. And everyone keeps saying that Harry looks a lot like his father! Hmm.
So: Snape had a love for Lily but he hated that she married James. Snape showed a lot of courage and turned against all of his friends and Voldemort to secure Lily and Harry’s protection. Snape did everything in his power to protect Harry. Snape only started being really mean to Harry when he started acting like James. Snape and Harry look a lot alike (both thin, both scraggly black hair, both big-ish nose).
It’s my thought and the thought of everyone I know who has seen the film, that there is more than meets the eye here. Perhaps we will find a true answer when Pottermore opens?
What do you think? Is Snape the real father of Harry or does he just want to be? Share your thoughts in the comments.
