I FF'd thru a lot. I might later watch more closely - prolly not
.Allison's comment
"See you back here in one week"
has me confused. (maybe I should listen to her again, but I swear that is what she said - or maybe she said "next week").
That weigh in was not live; did not actually happen last night, right?
So why try to confuse me?
If they had only one week between that weigh in & the finale, Grit could easily figure out the winner. No one is going to lose enough in one week to make a difference.
I'm not all into the trying to tie the show into real time - like Halloween & Thanksgiving. We are not stoopid; it was not Halloween when they had the candy temptation. They didn't fool me a bit. 
Not saying who is in the finale 3 in case some of you haven't watched yet.
But the F3 is no surprise.
