You are right, Jin definitely starts to realize things now. He didn't think that they were important, but now he realizes that they are important.
And you are right, for Jin it's difficult, because he doesn't know where Ryo is.

I'm so glad you liked the scene in the aquarium. And yes, there was already something off, but back then Jin didn't see it.

You are right, Jin will fight for their relationship!<3 <3 <3 <3
