I think on the third rewatch I noticed that the first line of the diary had a different meaning:
::: spoiler !“We were two young men at the start of a great career. Two young men devoted to an illusion. Two young men who never intended to hurt anyone.” :::
I was gonna make a joke that it’s also an idea that’s on so many street corners and coffee cups. However after googling I found out that it’s a siren on the Starbucks logo and not a mermaid. My joke fails on both humour and fact.
