Ne says, "This is how it lines up - are you seeing the connection?" Ne would use the chair, Fi would cherish it.
The opening scene, the chair is out on Juno's lawn, she's staring at it like, "YOU! It was YOU!!"...outside the lawn meaning, she's done with it, it's being moved out. Scrapped like the memory from the night. *lightbulb*
Then, she finds an 'use' for it. Right down to the lampshade sitting beside the chair - all recreated in the 'breaking the news' scene. Unless she's also Fi-attached to the lamp as well.
You're playing fast & loose with what YOU think substantiates as 'evidence' for profiling the character. How do you know that the author wasn't thinking about Juno's internal motivation - a view into her thinking/personality - with how the chair is used? You doubting, and saying, 'if anything it is MORE of a ....' doesn't hold much water unless you can back that up.Also, if anything this is more of a literary device than characterization of Juno. I doubt the author was thinking about Juno's internal motivations for using the chair. I think it worked well in the movie, though, now that I see that it was the chair she got boned in.
