MY THEORY WAS ALMOST 100% RIGHT

The next episode description says that Aku will discover a secret about Ashi that puts her in "grave danger."
I think it's pretty obvious that the "secret" is the relationship, and Aku's going to use it to screw with both Jack's head and his heart. How exactly? My guess is he's going to possess her and fight Jack, meaning Jack will have no choice but to kill her.
A little dark, yes, but that's just my guess.

WAIT A DAMN MINUTE
The preview shows Jack walking in the graveyard full of those old warriors.
This is where Jack met the Guardian in Season 3. He may be returning here to see if the Guardian's Time Portal is still active.
The episode 9 description states that Jack's "worst fear" will be faced here.
Jack's worst fear (besides losing Ashi at this point) is not being able to return to the past.
Guys.....The Guardian's Time Portal is gone. Aku destroyed it and probably killed the Guardian.
It's now impossible for Jack to return to the past. He has no choice but to fight Aku in the future.
SUCK IT
