You know when you're younger, and you're watching/reading stuff for the first time, and some things in it go right over your head? And then you watch/read it again, years later, and you realised what you missed?
I tend to get a lot of that. And, to be honest, if a thing is a joke, or an innuendo, chances are I still won't get it - for example, it honestly took me three years and an explanation from my sister to figure out why 'A Wizard's Staff Has A Knob On The End', from Discworld, should be a dirty song. *shrugs sheepishly* (That involved me actually asking my sister, saying I didn't know why this was dirty at all, saying the title out loud, and watching her struggle for a minute not to laugh in my face, before gently explaining).
Some of the things I missed were slightly more macabre, too. For example, you know the Addams Family movie, 1991? There's a bit in that where Morticia is pulling huge canvas bundles out of a wardrobe, checking their labels for contents. It goes: "Uncle Knickknack's summer wardrobe. Uncle Knickknack's winter wardrobe. *pause* Uncle Knickknack. *heavy thud*"
... See, what I thought she meant was, "Knickknack, Knickknack, again, more of Uncle Knickknack's stuff." NOT, "Knickknack, Knickknack, Uncle Knickknack's corpse." Though, in hindsight, considering this was the Addamses, I really, really should have suspected. *shakes head* Oi.
And then ... Some things you don't get because, as a kid, you just genuinely haven't the knowledge/experience to understand them. Things like:
Molly Grue: "Where were you when I was new? When I was one of those innocent young maidens you always come to? How dare you! How dare you come to me now, when I am this!"
When I was a kid, first watching The Last Unicorn, that scene was funny, watching Molly randomly yell in the unicorn's face, and kind of awesome, because Molly wasn't impressed just because, or afraid to yell at a mythological creature.
Watching it now ... I think that is possibly one of the most heartbreaking lines in the whole story. *smiles lopsidedly* Because when you're a kid, you sort of don't get what had happened between her and Cully, what her dreams had led her into. If you don't know the mythology of unicorns, you really, really don't understand what she's saying. So it's funny. And then, years later ... it's not.
And years later, watching that first scene of her, and then seeing everything she does afterwards, everything she fights through ... It becomes one of the reasons she sneaks up and becomes your favourite character. *smiles softly*
