That damage could be result of some beating that came from her family (her dad?). It was meant to warn both MC and especially Summer to dont pursue their relationship any more and dont try to contant each other. If one of them would break that it could harm both of them - especially him. So next time it would not be some beating but more serious attack vs MC. They were kids so they were both shaken by this event. And then they took her away. That would explain why Summer didnt (or couldnt) try to contact him online and why he didnt find her online - not to mention that its probably not established as a fact. We dont know what he tried to do next few years after her disapperance.
Or the damage is from a fall... they went to cliffs or ran somewhere and he just fell. Maybe its not directly connected to her disapperance.
If it would be about some "random dude attack" then it doesnt make sense that she would left and make no contact anymore. If some criminal would attack them and later kidnapped or killed Summer or something then there would be serious police investigation. And there would be some hints about it. And I think that if Summer would be dead Nami would not compare herself to her as she did in chapter 2 or 3. She wouldnt try to bring the memory of dead love up. But it seems like she is still "fighting" the memory of perfect Summer that MC has and cant get out of his head. It seems to me that the depression is not about the dead one but about the lost one.
It has only been stated that Summer's mother had an issue with Nika, no mention of her father. If he was beaten by him, that would probably be THE thing he remembers during therapy, not that her mother disliked him. I'm guessing Summer's mother is someone who had an issue with Nika's parents, more than the social status. They don't have a problem with Summer being friends with Nami. As for the possible random attacker, I'm thinking it's likely something to do with the gang mentioned in WiaB, especially if Nika is William's son. That brings us back to Summers' mother, someone screwed over by the town's resident pogo stick. As I said, Nika's dreams end when the police officer shows up so the police likely were investigating something criminal.
Now onto Nami, who has clearly harboured feelings for Nika for a long time. Why wouldn't she question Nika as to why he overlooked her and dated her new best friend? He saw Summer as perfect, despite her aggressive attitude toward him, Nami was always there for him but happened to be left by the wayside by both of them. Seems like a legitimate question, especially if they start pursuing a relationship, like "why am I good enough now but wasn't back then?".
Good thoughts! Still waiting for more material to get a better picture, as there's holes in every rationalisation so far. The holes are not erros, just, holes that we're filling in with assumptions, because we have nothing else to go by yet.
Some points to consider when discussing Summer's current status are:
- Elsa is her cousin. Elsa knows what happened to Summer. Elsa posts a moody photo on Aurora. She's a LI (or was intended as one). Nika will get in contact with her to find out about Summer, but something else (dare I say something Elsa? No?) will happen.
- Elsa's knowledge is important, because her mom was Summer's aunt. I can guess (assumption) that Summer's mom and Elsa's mom were sisters. 50% chance of being right. So if Summer disappeared, what happened to her parents? Elsa knows the full deal.
- Just to clarify, it's not only SUmmer who is gone, otherwise I'm sure Nami or Noji would go and ask Summer's parent's what happened. Whatever happened to Summer also caused Summer's parent's to leave Wollust.
- Elsa thinks moody thoughts about the past, in response to Nika's presence (the AUrora photo). So there is something serious there, and the way the caption reads, I'm guessing Elsa thinks it's something that will remain a closed chapter - there's a sence of regret for the way things turned out.
- Also consider Nia. Nika returns to school, yet Nia doesn't know what happened to Summer, and Nia recognises that something terrible had happened by the change in Nika's face. It's not just Nika pining for his absent gf. Summer's disappearance (and her parents) was basically immediate - Nia noticed Summer and Nika were away, then only Nika returned to school. There would probably be gossip at the school about SUmmer.
- Nika's accident is most likely unrelated. After Summer disappeared Nika got violent, he didn't waste away. He was getting into fights all the time, and was a solid athlete before. Then he gets taken out of school, presumably after the violent incident. That's when he wastes away and loses his muscles.
- it's also important to note that his depression was violent right after Summer left, and then he got into fights, and Nami was also acting up at school. So there is a post SUmmer period where Nika and Nami went to school, and then there is the period where Nika was taken from school. My guess is the violent episode relates to one of the fights, and it was over Nami. The school suspended him, and th charges we heard about were from the fighting, but they were dropped for some reason. He was probably told not to come back to school after that point, and he became apathetic while having nothing to do.
- also important to remember all the landmarks mentioned on the bus trip, such as the shops. That was from the times before he was a shut in.
These details don't help us discover what happened, but they do give us some pointers to pay attention to when we interact with Elsa, Emilio (when Nika goes to visit him to see what information costs), Amber (as Nika reveals more in therapy) and Nia. I think that in particular Nia and Elsa's paths will have revelations about Summer, and I kinda suspect that Marla's path will too (Marla stating that NIka is part of her problem feels realy weird, when she wants shared therapy with him, but not with Vic, her victim. Nika was just a bystander, why have therapy with him?).
Anyway, I'm looking forward to getting a few more puzzle pieces, but I'm not expecting we'll know too much more in the next update - I think we'll discover more about the Zanes, Petrovas and Reveras than we will about SUmmer. Just my gut feeling. Summer's too useful as a mystery this early on - IF OCean brings her in, it'll b a midway disruption point. Which is too predictable ina college game by far.
