There was something that has always been bugging me. It's actually several things I don't understand.

When Snape says "You almost died today, Potter", what does he mean? Maybe it's because I'm not a native speaker, but I can't understand that part. My best guess is that Snape got so upset with what Harry said that he almost killed him in his rage. But that seems very counterintuitive to me.

Second, Snape had possibly changed after his conversation with Harry? Does this mean that Snape took Harry's words and thought that Lily is actually not worth his love, after all these years? That's my best hypothesis, but I find it very weird.

Third, did I actually properly understood that he still loves her, after more than 11 years have passed? This is very unrealistic, people get over things, and I suspect that either EY is being unrealistic here, or Snape is simply lying.

Edit: I retract the last part. Still, this does not mean that now I believe this to be realistic, but rather that it might possibly be realistic. Also that EY could indeed have decided to just go with the canon, and I see good reasons for that.
