some thoughts I had about Subspace in particular, Medkit mentioned, somewhat heavily headcanon based but I'm also referencing canon a lot, I didn't give it all that much thought so mind the mess
Blackrock puts a ton of pressure on all their newspawn, you wouldn't expect anything else from a military region.
Subspace as an inphernal themselves were competitive in nature, on top of that they seem like a choleric to me.
That plus pressure and high expectations from Blackrock people and mentors and higher-ups turned Subspace into a person who is willing to sacrifice anything to become the greatest, be it people, relationships, gossip, misunderstanding, doesn't matter whether or not the bad reaches him, he's after success and success only.
In his spawnday video he states that it takes a lot for another inphernal to impress him, especially if they aren't from Blackrock, and also that he has a lot of respect for his superiors and basically he wouldn't be the person that he is if not them ("I owe everything I know to them!")
It's clear that her superiors had a great impact on her and what she believes in.
As a consequence of how she was raised and what she was told her entire life I think here is what has been going on:
– Mentioned before; great pressure on them (and others inphernals from the region) since spawnhood, probably alongside a justification that sounded something like "Blackrock demons got a reputation to maintain; we are above other regions thanks to our system" or something along those lines, that would tie the concepts together - "perform well, you're a Blackrockian"
– There wasn't only pressure, there was also reward for doing well what you were told to do, be it verbal or any other kind. Better treatment, better recognition.
These next few paragraphs are fully a headcanon, but I like to think that that year/years in particular when Subspace spawned, the newspawn who were around the same age were an almost fully failed "batch".
That the huge majority of them either died in spawnhood (stated to be common in inpherno) or they were average/below average, with the exception of Subspace, Medkit and maybe some other 4-5 demons or whatever.
So since young age Subspace was taught that life in his region was all about high stakes and high reward, but only if you perform well. So "perform well" was exactly what he did. Except someone else performed well too.
Medkit. Was just as talented and skilled as him, and they were approximately the same age too.
Maybe Medkit was the only one/one of the very few scientists around Subspace's age in Blackrock who was able to keep up.
Therefore Subspace's competitive nature + taught competitiveness made him want to, you guessed it, compete, she now needed not only to outperform herself but also her "colleague".
That whole thing with having to be better grew into personal resentment. It was a mixed bad, everything Medkit felt for Subspace and everything Subspace felt for Medkit was tied in knots, Subspace being a choleric made it ten times worse.
