Council of Elders
Further thoughts on theses memos:
Actually, it doesn't say many things about Maria but I think what it says is a lot. There's a vibe of resentment (and hints he may have suffered some neglect) but he turns around and wonders if Sage is like Maria.
Speaking of Sage, she's already made the comparison that Orbot and Cubot are like her brothers. So far, there's been a curious lack of bringing up Metal Sonic. I don't know if I just need to wait, they didn't think to bring him up, or if they deliberately aren't mentioning him.
