spoiler With The S7 Finale, I think Josh and Nicole Gave Us A Glimspe of What They Will Bring To The Table in Season 8

[bwrosas 252]

I think the S7 finale (wither you enjoyed or not) gave us an idea of what Josh and Nicole has/have in store for us in this upcoming season.

 

As far as the Pillars go, I've been thinking, that something is being set up that will cause them to go back to their original timeline in history, maybe they start losing whatever power they have or like Mistmane did in her story, start to grow older and in this case, weaker because they're slowly losing their power, and the only to save them is to send them back to their own time.

 

Also I think somehow we will probably find out the that there is something more Darker than the POS, Tirek, Chrysalis , or any threat they've faced combined.

 

I also think that all 6, if not Mane 7/8 Will get a vision of what this NEW Threat is, and what they may have to do to stop it, which may be something silmiar to what The Pillars did a 1000 years before to contain the POS.

But those are just my theroies. Do you all agree?
