well the people that say that are soooo wrong. it is 150% James but i guess they think that because snape loved her and in the beginning tu can tell she liked him before she met james. go to
link and in the beginning of snapes memories as shown tu will see his adventures with lily as children. tu will see that in their first año at hogwarts lily and james met in gryffindor and eventually got married and snape and lily were separated when snape was put in slytherin. tu will see that people must think this because of the amor connection between lily and snape, anthough james is totally harry's father, not snape. Also, later in the memories, tu will see that snape sends his patronus which is a doe (hmmm....) and dumbledore says "after all this time?" and snape replies, "always." hmm.... as tu can see, lily, james, harry, and snape's patronuses are all types of deer. so when tu hear this tu aren't really sure what this is supposed to mean and tu really don't get much help from the libros either. Some people think that to have the same patronus as another person tu must be blood-related somehow... which is possible but not really mentioned in the series, libros o movies...anyway, i think some people might get the idea from this misleading conversation o idea. por the way, this scene is in DH (part 2) when snape dies and harry takes the tears to the pensieve and vistas snape's memories. Also, something interesting: snapes patronus is not a ciervo, despedidas de soltero it is a doe, same as lily's. This makes me believe that if tu amor someone truly, your patronus is the same as theirs- it depends on what kind of situation. So because snape's patronus is Lily's, i guess people who believe the blood-related patronus thing must think that he is related to harry because harry is related to lily...Therefore, i think the reason why dumbledore says "after all this time?" is because he just figured out that because his patronus is a doe then he is in amor wth lily. and snape probably says "always." because he is saying that he has always loved lily.
