It's because they left out the mudblood friendship break up scene. Without that it makes Snape & Lily look like they grew up as vrienden and then into maybe something meer on the romantic level. Without the break up scene it makes them look like they were still vrienden up until to her death. Making it look like she could have had a secret affair with Snape behind James back. Then getting pregnant with Harry. To me I wish they added the friendship break up scene and her not forgiving Snape. It would explain things better.
I have to admit that I was a bit confused about if he was the father of not when I first saw The prince's tale. I had not read the book before I saw the film and in the film it isn't really clear that Snape actually told Voldemort tabout the prophesy (he didn't know that the prophesy was about Lily's son because if he knew that he would not had told Voldemort).
In the prince's tale (in the film) when Snape talk to Dumbledore they said:
"The prophecy did not refer to a woman. It spoke of a boy born at the end of July."
"Yes but he thinks it's her son. He intends to hunt them down now to kill them. Hide her. Hide them all. I beg you."
"What will u give me in exchange, Severus?"
When he said, "yes but he think it is her son" I thought for a moment that Harry was his son. But then I started to think. He couldn't be.
I don't get that either...I think the scenes are really dramatic which make people think what could have been of what alot of people wanted to happen Lily choosing Sev over James...I think movieSnape through the years learned to care about Harry I don't believe he loved Harry but he never wanted anything bad to happen to him... movieHarry he seems to be someone that hates seeing anyone die he went off and saved Draco in the RoR and has been a rival of his throughout the years & in the book Harry does see through Voldemort's eyes when he kills Snape so that could be another reason he showed feelings for him.
I think that in both the movie and the book, people have zei that Harry looks like James Potter, and they even showed his father. Harry looks nothing like Snape, which makes me confused on why people keep thinking Snape is Harry's father. But I agree that the main problem is that they left out the breakup scene.
haha...my mum and my little sister doubted Harry was Snape's son too after we watched the movie. It was because some people didnt read the books. Also,the caption of "Yes but he thinks it's her son." was wrong. It turned into "Yes but he thinks it's HIS son."XD Some people thought Snape meant Harry was his but James thought he was his. And the cadence of movie is quick. We dont have time to think.XD
I have always waited for one little sentence in the books, something like this: "He is your father, Harry." But it never happened. Call me crazy! I have known that it will never happen. But...isn't it human to think like that? u wish something that will never happen, want something special for the one u love...
