I love that Remus' good day has instantly undone any of the positive impacts of the other sides' good days because Thomas has now licked a stain on the carpet and vandalized someone else's car
Y'know, this brings up a good point - Did anything we saw in the video really happen?
In "meatspace," I mean - With c!Thomas. I think it didn't.
...kind of.
Both Patton and Janus said some interesting expositional/mechanical things:
Patton: "Whichever you pick, I'm gonna wanna do, which means Thomas is gonna wanna do it, which means you get to do it too!"
To me, this also implies the inverse is true - that Logan can only access certain resources (in this case, the library) when Thomas does. That Logan cannot access the library (or, at bare minimum, the new information it contains) without Thomas'... "permission," for lack of a better term.
So, what happened in meatspace? In this case, I think Thomas really did do all these things - But what we saw was the visual "translation" of how that affected Logan, how he was able to access the information from the external world.
[Roman and Virgil's segment didn't really address much about mindscape mechanics - Unless we count the SURPRISINGLY CASUAL (if it's canon) REVEAL OF ROMAN'S ROOM???]
Anyway - Back to Remus, via Janus:
Janus: "Have at it; I've convinced Thomas to lean into his intrusive thoughts for the day."
What I took from this wasn't that Thomas actually destroyed a car - Not only would that be pretty out-of-character, I seriously doubt that Janus would allow/encourage that - With him being Thomas' self-preservation and all.
However, this doesn't mean Thomas couldn't "lean into" Remus' suggestions and THINK about HOW he could destroy someone's car.
In meatspace, I think Thomas saw the badly-parked car and Remus suggested destroying it - But, instead of either extreme of suppressing the thought, or blindly acting on it, he instead thought about, in detail, what Remus said.
Which then allowed Remus to, in the Mindscape, act out what would happen.
This also explains why some of the alternate cards Janus wrote were... a bit much, at first glance?
I'm pretty sure Jan knows better than to let Remus actually try to kill Thomas' family (or walk into traffic) - But, letting Thomas face the nasty thought, and not try to deny it's existence/force it out?
That seems pretty in-line with what they've both been trying to do.
