If you want to know, in studster's past, he looks like this at the start of the animation but that's what his fact #2 on deck source of the ref of studster and studdings is talking about, especially it can be how it goes on the incident he had, while being on this after he died due to the mutations, he's now on somewhat colorful in void, but it causes him to be smiling and look up at it, especially this place it causes happiness (idk this can be inspired about jax's abstraction dream or so), in so a few minutes later while he's relaxed here, he got revived himself.
