Thanks!

I'm glad you liked it.

My whole reasoning wasn't based on the fact that two people couldn't have the same type of animal as a patronus, as you have pointed out just like there can be different kind of deers there can be different kinds of cats, dogs and so on, but that two people couldn't have the exact same patronus. That the theory that goes around that Snape's patronus was a deer because his patronus was Lily's patronus didn't hold to canon facts. I mean, in canon, only Harry says that and he deduced that from the memories he saw, not from something someone actually said or because he saw his mother's patronus.

Then you have what Lupin said and what JKR herself said in interviews (I found out after I wrote that AN) that two people couldn't have the same patronus. So Lily and Snape couldn't have the same patronus. But in my understanding Sanpe's patronus did represent Lily. So why would it be a doe then, just because she was a stag Animagus wife? You could think that. But isn't a patronus representative of the person casting the Patronus? So would Snape think of Lily as Lily Potter (James'wife) or Lily Evans, the girl he knew? I personally don't think he'd link her to James. I think that for him she'd always be Lily Evans, so my reasoning was that the doe had to be something about Lily not James. Why not her Animagus form if she had tried to be one? To me that made more sense than his patronus being a doe because James was a stag and Lily was his wife.

So this isn't about two people not being able to have the same animal as a Patronus but of, in my story, Lily being Snape's paronus and him knowing that and therefore realizing what the doe meant. That she was a doe Animagus. Was my way of rationalizing canon facts and inserting them in my story.

I hope that cleared that up!

Thanks again!
