Hear me out, no, fucking listen to me.
Victim has DID. Each past death + clones are an alter, the last one who survived is the host that split into two: one being the one left with memories of Mitsi and the other being the one we see front in the box.
Soon after AvA10, Victim realises that TSC is in the early stages of the same disorder with most of the alters not being very conscious.
Therefore, instead of trying to help or leaving it be, Victim Rocket (the host) purposefully worsens the situation and makes Orange split a shit ton of alters by various ways of torture and manipulation. Their alters try to stop them, but they can't. They're too weak to front.
They tell Shady Smith that it's to benefit from the kid's powers easier or some shit. But in reality, they see their "weak selves" (the rest of the alters) in TSC (+Yellow and TCO). They're trying to be "the superior one in the power dynamic". They are trying to control their surroundings.
Cowboy manages everything in The Second Coming system and puts Orange (the host) through many puzzles and challenges to keep them distracted and away from the front... away from whatever horrifying thing Victim is doing to them...
Victim knows the host is hidden deep in the mindspace. They try to lure the host out bc they deem the rest of the system useless. Orange tries to get out of there after realising what's been happening. Cowboy can only keep them* safe for so long...
*Every sentient being you see in AvE and more... (Yes, the Math symbols and the multi-dimentional creatures are alters.)
