Jade, you poor idiot.
After her alchemy binge and a couple awful conversations with trolls, Jade sets out to contribute to her teammates’ efforts by developing her own ability as a Witch of Space. Not knowing what exactly that entails, her first instinct is to go around viewing her teammates’ physical locations.
This isn’t Witch behavior at all! She’s acting too much like a Seer, meaning she hasn’t yet recovered from her class inversion. So as unofficial Seer of Time (note the red goggles!) what does she actually end up looking at?
Which brings us to the question of why she inverted in the first place. We’ve always known about Dave’s collection of preserved dead things, and later Aradia explicitly pointed out that dealing with the Time aspect means confronting death:
AA: alpha dave still has a long way to go
AA: hes still not at ease with his mortality
AA: but people like us have to be!
And what had Jade already told John about her own mortality, hundreds of pages earlier?
GG: its nothing that secret or personal or anything….
GG: it is just something kind of sad and weird for you to see
EB: what is it?
GG: it is my dead dream self
GG: it has been there for years, i always knew i would die but i did not realize it would go like this….
