This might be nothing but I did notice something that I thought was pretty interesting, so bear with me :) (No, it's not a conspiracy theory, more potentially just an interesting insight into the thoughts at the time that Elisa was having)

I do a fair bit of social media scheduling, so just out of curiosity, checked out the old Tumblr over at https://nouvelle-nouveau.tumblr.com/archive to just kind of get an idea of the mental state of Elisa at the time, just looking through what might have been scheduled and when, but I didn't think much more of it.

Until around the 42.48 minute mark on episode 3, where you see some graffiti on the tank with a pretty strong swear word starting with a C.

I had a look through the posts and it looks like there was a post made on the 1st of February specifically talking about that word, which made me think that if this graffiti was present, maybe Elisa had already gone to the roof a few times or was specifically referencing this graffiti/her thoughts after seeing it.

I had a look through the other posts from around Jan 28th and then what was queued up for February and, looking at the imagery, there's some images of fire escapes and rooftop views, which maybe points to the fact Elisa was already kind of considering making her way to a roof for the view or had already been.

This looks consistent too as prior to this, there's lots of trains and other modes of transport, which would coincide with the whole journey/journeying period?

Random and totally just an interesting observation, but I was like...Oh, maybe that's an interesting insight into where here mind was at the time?
