@hj Hey, thanks to someone on the channel of Pepper&Carrot, I got the ref : https://en.wikipedia.org/wiki/Loss_(comic) , Interesting article. First time I read it.
I wouldn't say it to be close but I understand.
However, I propose here a real ending and twist: the cocoon is not a loss or a convalescence, but a process done by her body for metamorphosis. The ray of light at the morning symbolise this hope.
That is how I perceived it. She was sad about her state but did not see that she was transforming.
I love it.
