Lorrain Baines in _Back to the Future: Part 1_ is
not concerned much of her safety, a mix of innocent/bad risk teen behavior.
During the scene when Lorrain is on a “date” with Marty she makes a reference
to her mom’s liquor cabinet. This gives
a context to a believable back-story.
In the scene with car outside the Enchantment Under
the Sea Dance when Biff comes it’s same consistency with lack of safety or
awareness.
She says, “Some one’s coming.” to Marty as more of a happen stance, but a
wiser more self- aware person would have opened the car door, bolted and
hid.
She needs to be there for the upcoming scene to see
George McFly punch Biff. She isn’t a
mature woman who can save herself. She
needs to be saved in order to fall in love.
It’s a tired story line as far as love story plot is concerned. I would strive to write a way where love
could happen without a woman needing to be saved.
