That's the thing!!! C!Thomas could probably benefit from indulging in dark creativity, be that breaking something, writing something gruesome, or in general just screaming really loud. He hasn't ever really fully leaned into that and I think it'd be good for him to have that catharsis.
But dark creativity and intrusive thoughts are not the same and can't be treated that way regardless of the fact they are combined into the one facet.
Especially in WTIT where he's fully leaned into the intrusive thoughts role.
Dark creativity is generally beneficial to Thomas because giving Thomas a greater perspective for his art is useful. However, intrusive thoughts are never helpful, and none of them have anything to do with the actual issues Thomas is dealing with. Generally Remus is much more likely to emerge and cause chaos when Thomas is already upset or anxious about something else because when Thomas is already feeling low, it is easier to further upset him. You could say that Remus showing up is beneficial to the other sides to indicate to them that Thomas is upset about something, but nothing Remus does has anything to do with his actual issues or realistic problems, he is just creating more anxiety and chaos because it is fun for him, and that anxiety and chaos that Remus causes has nothing to do with Thomas's actual real life issues, they are separate.
As someone who also has intrusive thoughts (twinsies, you and me, I want the window seat), I agree that Remus works like a litmus test, but more so like a check engine light. The light comes on when something is wrong enough, but the light itself does not tell you exactly what is wrong. You have to go into the system, you can't just trust the light. Remus comes around when something is wrong, but hes not giving any good indication as to what. He's playing to sensitivities and insecurities, and while those things are stuff to work on, they are not the root problem. He's misleading.
The issue is that, if Remus is showing up to show something is wrong and he's trying to help fix it, he's going about it in the literal worst way possible. He's not helping by making Thomas anxious and giving him Intrusive thoughts. And he's not really trying to guide anyone to a solution either. Yes he tells Logan he can't fix Thomas by himself, but that's more of a dig at Logan specifically cause Logan would want to fix Thomas by himself, and he can't. Remus is enjoying the misery.
He may be recognizing something is wrong, but he doesn't seem to care about the solution. If anything, it would be more beneficial for Remus if Thomas was to remain upset and anxious cause that's when remus is more likely to be listened to and kept around.
On one hand I can agree that it might be a disservice to reduce Remus to shits and giggles. How ever, he hasnt really proved much reason otherwise. In general I actually do believe he is in it for shits and giggles and that his character is that one dimensional. He's shallow enough that he would do things, and has done things, for the soul purpose of making someone upset or because he thinks it's funny.
The only solution I can see him being a part of is pushing Thomas so far to the breaking point so that he does indulge in dark creativity, but if he does that, he's not doing that to fix things, he's doing it because it's going to be fun.
In the end I think we just have a fundamental disagreement on what Remus motive is. I just haven't seen anything that indicates he wants to help as a whole. He likes poking the bear "just because" in my opinion.
But I do still agree with original sentiment, I think he's incredibly clever in the way he does what he does, he knows exactly how to get under everyone's skin and takes full advantage of it.
