I had pegged Jake as being a voyeur purely for the sake of being a voyeur, because you know, that’s just what fourth wallers do - but cen is absolutely onto something in speculating that he was really using Jade as a scrying orb (“harvesting inspiration” in other words) hell, what was I saying just the other day - Jade is Jake’s “seed” in exactly the same way the cue balls are Scratch’s seeds, of course he’s going to be using those seeds as crystal balls the same way
reapplying this to cocoons-as-computerised beds obviously ponders whether Lord English is ‘looking for something’ in the minds of his subjects (who also have his seeds planted in their heads); but that’s also the conceit behind the fanadventure in my head so i’m both biased towards and warily against it as an interpretation of Homestuck
