TRUSTFELL NOTES
Isaac's room is ridiculously neat - you'll notice that there's nothing out of place and nothing looks cluttered. You can find most of his belongings in his trunk, though all the items he wanted to keep are in the closet. There are some notes laid out on his desk as well, addressed to the other people here (and one other person).
Those might not be the first things you see though, since there are the designs painted on two of the walls. You'll find yourself staring at a map of Amestris with certain cities labeled. Ishval is circled in red. Some of them have paper duct-taped nearby with Isaac's handwriting, written in code of course.
The second wall has a map of Central City with a familiar alchemical array painted through it in red. Three specific points are marked on this map and once again there's duct tape and paper containing notes on whatever it is this one's supposed to represent.
Inside the desk you can find an alarming amount of notes - they're written in Amestrian and coded in a cipher that involves numbers, letters, and mathematical equations. If you're able to figure out the cipher you're certainly welcome to read them! Otherwise these are coded to look like research notes on his alchemy.

I like him, he's got a pretty great sense of humor. I don't trust him, but that goes without saying.
WEEK 2
We talked a lot about alchemy and the type of magical science he uses in his world. Sfeers sound really interesting. I wish I could see them in action. Luca says he can't use them though, so I'll try to be a bit more sensitive about that.
...I don't think he'll be a threat, but I can't let my guard down for anyone.
WEEK 3
He's really good at chess. I've ever met anyone who's that good. Luca beat me three times and asked about the scar on my back since I lost the last game and... well, I told him. It feels like there's not much of a point in keeping it from him. I guess I'm just really fucked up by all of this? I don't know.
WEEK 4
I kind of accidentally told him about Kimblee and now he's also got the wrong idea. Why does everyone think I'm interested in him!?
WEEK 6
He was trying to make plants grow with his array. He knows so much about it and yet can't use it... that really is depressing. I feel bad for him. I hope he's able to use it at some point.
WEEK 7
We didn't get to clear up how awkward things are. Maybe that'll make this easier.
