I don't even think that was the intent Ocean had when he said that Sasha isn't Summer. Knowing him, he just wants people to treat Sasha as its own character and stop theorizing about stuff that is most likely not true so it doesn't ruin the personality that he's building for Sasha. I guess it would kinda suck trying to build a new character up and all people will think is that this character is someone else.
Hope you understand what I said, I'm not so good at explaining myself sometimes lol.
She may be related. She may know something.
All this for me is a red herring. Nothing more.
All the events that lead to Sasha being Summer are simply because the reader knows it is a mystery. And in some sense it is waiting for clues.
What do we know about our beautiful scar face goddess of war? Nothing. She having the same earring may be an old Nami's friend that has nothing to do with Summer. Or she simoly find it weird they share it.
But again, Summer=Sasha with so heavy "clues" would be a terrible choice.
Clues have to be subtle. Even to go the path "i make them obvious so you discard them" does not really work. If you thought about the possibility, when the mystery is resolved the surprise effect is very dimished. "Ohh yeah I thought it would be once" is not the same as "wow, I never would have imagined that"
when you ask her if she is, her response will be clear! "no, i am not! summer died to the monster in the cabin 6 years ago!"
but you are right she is a goddess of war and loss the threshold that separates boys from man into the eternal suffering that is the life of a man, the mythical prison described by Schopenhauer from which no man can ever hope to escape except trough the fire gates of self determination when one takes his own life!
Well, i just did it. Hope this is not the bad idea and I don't cause him any trouble. Finger Crossed
WIAB as not been abandoned that only takes time away from his work! have patient cause even tough not everything that comes to those who have patient is good everything that comes to those who act rashly is bad!
Okay. So. Sasha might not be Summer. I'd guess that she knows Summer enough to be told the story of the erasers. That's why she had a face of recognition.
On a side note. Why is it all Asian characters in these games know martial arts? That's stereotyping. Just once I'd like to see some Asian characters say the closest they came was watching Cobra Kai. LoL
its a cultural link to mitigate the homesickness that those parents feel and thus teaching it to their kids is a way of keeping them in touch with the home culture!
I saw this among st the Portuguese community in Germany and France, their attachment to some music styles and dances was surprising since most of the youngsters in the home country have shed those things a long time ago while its still alive and half of the kids in those communities continue to practice it while in the home country perhaps not even 0.5% of youngsters bellow the age of 25 know or practice it!
The Portuguese community in the Philippines who have been separated from the main Portuguese culture for 500 years still keep many traditions that are now sadly dead in Portugal!
so i assume martial arts for Asian emigrant communities must be like dancing for the Portuguese emigrant community or practicing capoeira for the Brazilians! its a statement of identity!
It's impossible to tell at present; all we can do is guess.
