Since I have a bit of an advantage knowing Japanese... gonna help out a bit here since there's a few context that's left out.
1) Set's the one talking in last few dialogs, proof is the untranslated Japanese text on last page, says "Set's thoughts leaked...!".
2) Osi probably has nothing to do with, or at least none that we know of yet with time travel. So far all the dialogs point towards him being ignorant to reasons his brother has changed. The last few dialogs was not him talking, it was just Set being all beat up emotionally towards his brother not supporting his change.
3) Thoth is suspicious. Go back to first chap if you doubt me. Why the heck is he trusted right now. He's obviously suspicious from day 5 years from now.
4) Bromance is not BL. Bromance is the holy grail. ...Okay that's opinion, but also fact. I don't think it'll turn into actual BL tho, the undertones are too weak for that.
