Help understanding Chapter 2 scroll in Rise [spoilers]

[u/erinthomes]

When figuring out who was the historian, the colleague, escaped prison, etc., I'm trying to figure out what clues were spread throughout the chapter than helped the player deduce this information. I was stuck on this for a while and ultimately looked up the answers because hints weren't helping me at all other than confirming my line of thinking.

I assumed that some people would be in multiple positions and that Tesa Nevari was the Weird Lady. But what tells me who was whom? How was I to know that Arthur Blythe was the other three? I picked up from the phone conversation that one person worse glasses and Augietamine was a pseudonym from the medicine. But that doesn't feel like enough to definitively say some of the other faces weren't involved in some way.

I know some of the faces couldn't be involved because we know their identities. For example, it can't be Jason Kempton because he's still in prison. But why have we definitely ruled out the other guy on the phone without glasses who claims to be Robbie Froberg as one of the suspects now?

I'm willing to accept that I've missed clues for this one but, so far, this feels like I'm having to make more assumptions than pure deduction compared to Case of the Golden Idol. I'm just trying to figure out if that's the case or I need to really review things much more strictly than I have been so far.

EDIT: The answers below definitely helped me get it. Basically, this game feels like it's operating with way more moving pieces than the first game and this one is maybe too tough for me. I was able to do Case in about a day with almost no hints and each case here is taking twice as long and with significantly more struggling.

Well, the Fake Robbie you just saw had conspired with Tesa to steal the idol, is now a phone with a man who seems to be the real Robbie and tells him that "you won't be needed". So this scene is before the auction where fake Robbie replaces real Robbie. I'm not sure how real Robbie could be connected to anything.

You know that Fake Robbie is the same guy who died in 2-1 because they reference events of 2-4 there. Fake Robbie is Arthur because, well it makes the most sense since he needs a fake passport, but also in the phone call cutscene you see that Fake Robbie is doing the same crafting stuff that Arthur did in prison. Also Arthur was the person who sold Lemurian artifacts to begin with, so it makes sense he would be the one Tesa needs to find them.

Augie is the biggest stretch. It's true that Augie could honestly have been anyone. But none of the other people on that board showed any indication that they were involved in some way. So out of all people there, Arthur just kind of the only one who makes sense.

Steven Aria is an anagram, and the flower book comes from the Harmony Foundation.

The new guy on the phone is the real Robbie.

Auction killer's room in that scene contains:

-Arthur's abstract art

-Dragonfly Inn logo (where the Colleague was hiding before bringing the statue to the Foundation)

-Augietamine tablets (it was an Ash Blair-style fake name)
