I'll break the ice. When I went through the script this time, I tried to clear my mind that I had read the script before and seen the movie a couple of times, go at it fresh.
Doing that, I was struck by Juno's distinctive voice: a wise-ass beyond her years teenager. If you go to this
interview with Cody, she says point blank about Juno, "She's a lot like me," so that could come off as inauthentic, a character who is
really the screenwriter, at least in terms of her dialogue.
But I didn't read it that way this time. Here's a young woman, Juno, who was affected by the break-up of her parents marriage. Check out this dialogue from P. 15-16 of the script:
My dad used to be in the Army, but
now he’s just your average HVAC
specialist. He and my mom got
divorced when I was five.
She lives on a Havasu reservation
in Arizona...
... with her new husband and three
replacement kids. Oh, and she
inexplicably mails me a cactus
every Valentine’s Day.
And I’m like, “Thanks a heap,
Coyote Ugly. This cactus-gram
stings even worse than your
abandonment.”
It's not much, almost a throwaway set of sides, but apart from the exposition of the divorce, the sides convey at least two more things: (1) The break-up happened when Juno was 5, a particularly vulnerable age when a child is deep into learning about
trust. (2) Juno still
hurts from her mother's "abandonment," the pain still stings.
I put those two together and that helps me understand why Juno has to act cooler than cool, hipper than hip. She
thinks she has moved into adulthood, at least part of her believes that. As an adult, you can do what you want to do, act the way you want to act, you don't need to
trust anybody else. Juno has in effect bypassed her adolescence and jumped straight into adulthood [again what she she believes about herself].
Thinking about her decision to have sex with Paulie, I think it was that 'adult' part of Juno at work: what's more adult than coming onto your boyfriend and having unprotected sex? Okay, not
rationally perhaps, but the actual daring nature of the act is saying to the universe, "Screw you, I can do what I want to do."
Seen in this light, Juno's journey is about trying to be an adult - with her pregnancy - and yet eventually realizing she's still a kid.
On P. 88, after she has had it out with Mark and Vanessa following Mark's decision to get a divorce, she returns home and her father asks how she's doing. Juno says this:
Dealing with stuff way beyond my
maturity level.
Part of her metamorphosis, capped off by rejecting the cool, hip adult Mark for the geeky, unhip teenage Paulie. So in the Denouement when instead of driving a car, she rides her bike to Paulie's house and they sing "Anyone Else But You" together, there is this moment:
She and Bleeker exchange glances as they play. They smile ambiguously. Juno leans over and kisses Bleeker on the cheek.
Pull out to reveal the surrounding green suburb buzzing with life and summer activity.
That little kiss on the cheek is a bookend to the script's second scene:
FLASHBACK - Juno approaches a boy hidden by shadow. He’s sitting in an overstuffed chair. She slowly, clumsily lowers herself onto his lap.
Now she can be a teenager. Now she learn to trust through her relationship with Paulie. Indeed her experiences have helped to ground her in her family, the here and now, so she can settle into who she is and not try to run away into adulthood early.
How does all this tie into Juno's voice? Because her wise ass beyond her year's dialogue fits her psychological state, trying to be an adult, trying to sound like an adult. She uses hip and cool lingo, beliefs, and cultural likes / dislikes to distance herself from being a teenager. It makes sense logically for her character and, thus, I would argue is an authentic expression of who she is.
