Let me ask you this question. I'm bored out of my mind at the moment.
When you first play MeChat, were you able to tell who is who? I'm talking about Noel. I picked Noel first before I saw Sam. It's a first rule of mine to pick the first character, complete their story, then replay it with their counterparts.
Anyway, I already can tell who Noel is just by how he is talks in the text. I mean compare him to Jason who looks like your typical anime character who rarely express any emotions.
Sam and his Jason however will make me confuse to who is who. Both look cheerful. It is until the first date you get to know.
Back to the Jason with Noel, I had paid and seen the cgs, I see Jason smiling which I find it to be a surprise. Can you blame me? I had watched too many anime growing up.
Jason reminds me of current Wakasa. Waka doesn't express any emotions and it happens when he was young. I still believe it involves Shin's death.
They don't show any emotions when they first appeared. Jason wasn't seen when he confronted Noel. It could happen once Noel's story gets an update which will be a long time.
