I don't know if people will consider this a spoiler or not, but I'll put it below the cut.
This is the blurb from TVGuide.com (and my DVR) of the description for Odyssey:
In the eighth-season opener, the Justice League searches for Clark, but is stymied by the new CEO of Luthorcorp, Tess Mercer (Cassidy Freeman); and Chloe is held prisoner by a group who have discovered her powers, while Clark has been stripped of his by Jor-El.
I don't remember knowing that it was confirmed that it was NOT the government who had Chloe. Sometimes it's hard to keep track though. Also, I don't remember knowing for sure that it was Jor-El who de-powered Clark, but I guess that's common sense. Who else would it be?
Also according to TV Guide, the CW will be re-showing the season premiere on Sunday, Sept. 21 at 5pm which I'm assuming is Eastern time.
