So...Tachibana's real identity

That’s still just a theory, don’t count your chickens yet.

I had this thought too, since Rin/Jin sound similar, but they look totally different. We'll see what they throw at us as we get more clues... Could be a red herring, you know.

they barley had any interaction or, unusual amount of interest from jins side at least. if there was then maybe.

but no, when they did meet briefly. nothing happened.

maybe the real jin is nana's brother? no evidence for it, I just think it would tie the mystery coma dude into the story better

As much as I like "Fake Jin is Kyouya's sister", nothing is confirmed yet. But we can have our hope.

I feel like she would have tried to interact with her brother on the island more, no? Instead of with Nana, Tachibana would have wanted to work with Onodera Kyoya. But the first time Tachibana and Kyoya meet was when Nana confessed.

Well it is still possible. We do see that >!Tsuroka has Rin in his captivity so maybe he forced Jin to revert to their orginal self which would be Rin if the theory is correct.!<

That would make sense why Rin’s hair was long because if she could transform then it would make sense her original body to grow even if she was Jim the whole time
