I understand that I've talked about this subject before in another post, but I just randomly thought about it again yesterday and decided that I want to rework it, as there's some details I want to add to it now that I'm thinking about it properly again.
Anyways, we all remember this scene and the covered-up portraits visible in the background in s2 e8. We all talked about how it mirrors the fact that Blitz scribbles out his face in the pictures he has at home, and I definitely agree with everyone there that it is a parallel of sorts, something else that I noticed that no one else really talked about to my knowledge was the fact that this also was likely foreshadowing some of the events of Sinsmas.
Looking at the image itself, it's pretty obvious that the main detail here is the fact that everyone within the portraits are covered up entirely, with the exception to this being Octavia, which shows that within the portraits, Octavia is alone and all by herself within the family, which bares resemblance to Octavia following the events of Sinsmas, which is the reason why I believe this was a bit of subtle foreshadowing.
During the Sinsmas episode, we see Octavia permanently cut Stolas out of her life, for now at least, which as a result, has effectively left Octavia entirely alone and by herself within the family.
Because as we know, Stella is objectively an abusive + neglectful mother towards Octavia, and do I even need to explain Andrealphus at all in regards to this topic?
Which again, effectively leaves Octavia alone and all by herself within the family following the events of Sinsmas as a result, which, as I've stated before, bares quite a bit of resemblance to what the covered-up portrait seen in s2 e8 could've also been symbolizing.
Much more on why I believe Stella is both an abusive and shitty mother towards Octavia here:
And that's without mentioning that there isn't any strong evidence within the show so far to suggest that Octavia has outside friends that she regularly communicates with as well.
In conclusion: I have presented and explained a reason why I believe the covered-up portraits seen in s2 e8 may have been subtly foreshadowing some of the events of Sinsmas.
