I did get a hold of a video of last weeks live show where Julie says on next weeks Wednesdays live show.
I'll quote her here and she says it closer to the end of the video.
My thanks to MenOfBigBrother for capturing it on video, thanks again.
"And America its time for you to get involved in the big brother game
Evicted houseguest Jacob Jen Parker Amanda and Alex have not returned to their regular lives
Instead they have all been isolated from the outside world
and have no idea what’s been happening inside the big brother house
With your help one of them including newly evicted houseguest Allison
will get the chance to shake things up by returning to the game
Go to cbsc.com and vote for the houseguest you would like to see return
Then next week see if your choice makes it back into the house"
