Severus Snape | Important Scenes in Chronological Order

You are remembered, Alan Rickman, February 21 1946 - January 14, 2016. Severus Snape's most important scenes and arcs in the Harry Potter film series in chronological order, from meeting Lily to his memory living on in a name...
I made this video to counteract the overwhelming amount of Snape hate I've seen on Tumblr over the last couple years. Thank you to everyone who has contributed subtitles! I want this to be as accessible as possible so it means a lot.
Alan Rickman portrays Snape's character beautifully, withholding of emotions when necessary, which makes the pain he expresses later all the more powerful. Something about seeing that emotion only as bookends of a numb life makes Snape's character more tragic.
To consider:
Double-meanings; in dialogue, for example, when Remus is talking to Harry about Harry's mother (seeing the beauty in people), and Severus talking to Harry about "controlling his emotions" (something he's had to do for most of his life).
What the movies left out (if you haven't read the books, you really should!); such as Snape's debt to James and calling Lily a Mudblood.
Character motivations, such as; no one loves or rightly trusts Snape except for Dumbledore; Snape treats Neville the way he does largely because Neville could've been the Chosen One instead of Harry, thus Lily wouldn't have been killed (and Neville probably reminds Snape of everything he didn't want to be as a child); and Snape sees Harry and Ron as James and Sirius.
Character arcs, such as Snape how views Harry: first as a copy of James, then as Lily's son, and then, I would argue, as "just Harry."
Be sure to give your opinions on Snape's character in the comments!
