Didn't summer know about s1 and was telling Jimmy and maybe Shinji all about what the show is about, so why would she then suddenly act like it's the Truman show all about her when she was explaining the concept of the show to others? I feel like something else is actually what set her off and it probably has to do with Shinji. Wasn't she fine when she was cuddled up with him and then they went to a bathroom together and then she stormed out and started all this shit? I'm trying to remember what happened
Because mental illness of her kind doesn't work logically. I can believe that Summer watched S1 and thought she could handle it. I can just picture her during her sane moments thinking she could be like Letty; bullied but she can make it through and win, or at least become a fan favorite if she didn't win 1st place. Letty's character growth was inspiring, and Summer also said before that she wanted to be on this show to prove to herself that she isn't weak. Everyone who joins probably thinks they can tough it out, only for reality to hit them hard. They're stuck in a small space with strangers, some legit crazy, and they are cut off from all the basic comforts in life that they've come to rely on.
They can't call or text friends, they can't hop on the internet and scroll mindlessly. They can't get in their car and go somewhere, and they can't even simply relax by themselves. They're stuck in a small house with worsening conditions and they're forced to hear TTS say things that hit too close to home. Even if the messages don't bother you, it still gets annoying to hear gross SFX and JJJJJ over and over again. And remember, you have to put up with this for weeks.
This would be tough for anyone, but even worse for someone who's clearly mentally gone like Summer. When she's having legit manic episodes, logic goes out the window. Eventually she will come down and realize her fears are over blown, but this is short lived until the next thing stresses her out and triggers another manic episode.
It doesn't help her mental state that her worries about annoying everyone else end up being true. She seems aware at times that her breakdowns annoy people, which makes her more stressed out and paranoid that people are talking about her. She's right that people are talking about her, but only because they're worried, not because they hate her. She's basically creating her own cycle of hell.
I don't know what Summer needs, but being on Fish Tank clearly isn't it.
