This questions's just haunting me since I've read Deathly Hallows;
What does Dumbledore mean with;
'After all this time?'
It's in the part where Harry's seeing all of the memories Snape gave him while dying,
Dumbledore asks Snape to kill him if time has come and they have a fight bout it
Snape sent a patronus but to who? 'Always' he answers to Dumbledore's question.
I can look at it for hours but I just don't get the point.
Is here anybody who does?
