What if dave put his hand in the juju Thingy? What about rose? Jade? (Of course since Noone truly knows but hussie, I'm asking what you think it would be)

No idea, again it’s sort of hard for me to say because on a fundamental level, as I said, I don’t know if it gave a combined power or hypercharged John’s power or just added the Plot Retconning as a thing apart from the 4 Betas’ aspects. There’s a lot of symbolism in the Comic, and the Treasure Juju is the centerpiece of this Symbolism, it’s the manifestation of the fact the Kids are trapped- In three different ways. Literally, as them, or a different Timeline version of them literally got sucked into the Juju, Metaphorically, as they’re all trapped in Lord English’ Timeline, and Metaphysically, in the fact that they’re characters bound to the plot of the comic.

Caliborn becoming Lord English and trapping them are tied together- Him becoming the Villain, his rise to infamy, the set-up of the Alpha Timeline… So it only makes sense that his Downfall would come from the same Juju being used against him. And in the same time, it’s only that Juju that could provide John with the ability to escape the story. Because it’s a manifestation of a self-fulfilling prophecy, of the Beginning, and the End. Of the Plot, the Storyline.

When I say “I don’t know”, it’s not that it’s just too vague- It’s that the symbols are too densely connected. John is a Heir of Breath. Changing, Direction, Plot, Leadership, Freedom, Detachment, his powers speak of the very core principle of the story- Escaping. Fleeing the inevitability of the Alpha. Space and Time represent the core of how Reality works, with Light being a fortuitous outcome, or broad knowledge of everything, and Breath representing this detachment, and the way the story develops as a whole. All four combined can very much be said to represent this plot-changing power.

See what I mean? The Treasure in itself. The combination of those 4 Aspects. John’s Classpect. The hypothetic of what would happen if Jade touched the Juju is interesting, and it’s up to anyone’s guess! But as a story that relies so heavily on symbolism? The thing is. It could’ve never been Jade. John, touching the Treasure, with the 4 Kids trapped within, was the ONLY way the story could’ve developed, keeping with its thick web of symbolism.
