What if Zoe doesn't actually have Heterochromia?

So I think it's heavily implied that Zoe's purple eye is not exactly natural. However, I think most people have attributed this to the Aspect of Twilight imbuing her with its powers and Rioters have said as a character of change, etc., the eye fit with her thematic.

However, In both Zoe's lore as well as in some Riot posts of people connected to Zoe's story, it's heavily implied that while she exists mainly in the present, she can warp time and reality to visit the past or future as well as see it at any given time (assuming Zoe actually wants to, she's the real character who goes where she pleases). Therefore the question has to arise, what if Zoe's eye wasn't natural or caused by the Aspect of Twilight, but what if that eye has been affected by the Void which only Zoe has seen? She could have physically visited a future Runeterra that is completely consumed by the Void or she could have simply seen into the future and her eye is just a reflective surface on which what's in the future can be seen (a lot of purpley Void stuff).

If you were a conspiracy theorist going one step further you could even guess that Zoe has been infected by the Void. In Nami's comic we see the old Tidecaller with full on purple eyes and decaying skin completely changed by the Void. The power the Aspect has is making the process of corruption take centuries longer than usual in Zoe's case. As you all know she also has extremely long, purple, and magical hair, and if the Aspect wasn't there who knows? The star filled and weirdo cosmic hair might just take the shape of tentacles.

Personally I think the former theory is true but the latter isn't, but it's still interesting to think about for when we get the next Void champion and Void lore update in 2023.
