I actually think that Jade is prepared for Ed to go tonight, as much as she doesn't want it to happen and hopes she's wrong. She knows that Tim nominated Drew and Ed and she considers Tim the house mastermind so she thinks it's between the two of them. Tim has talked to her about "keeping Ed in the game", alluding to some reason that wasn't clarified, but Jade knows she can't trust him. Of course, I think Tim really DOES want Drew to go this week, but I don't think it's happening and Tim will be happy to gloat about Ed being his target all along.
So, the eviction isn't going to be a complete blindside and Jade will cry, of course, and everyone will hover around in sympathy, but I think she'll be mostly fine, not wailing and sobbing. That's just not her. What I do think will make or break her ability to bounce back is what he puts in his good-bye message. I'm not really sure what will be good or bad, because Jade can zig when you think she'll zag. If he's all "Bye, Jade, have a nice life" I can see her totally stuffing everything down and putting on a stoic face, saying, "Well, he never promised anything" so the others don't know how hurt she is, or going the other direction and dwelling on it incessantly until everyone and their mother (well mainly Mikkayla and Madeline, because that's who she'll talk to) wants to go deaf rather than hear any more about it. Same with if the guy suddenly has some kind of emotional moment (or a brain aneurysm, same thing) and starts talking about their future. She'll either be so happy she'll be bouncing around the house, or desperate to leave to keep him from changing his mind.
Keep in mind, the brushoff is about 99.9% likely to occur, so we should all be checking the live feeds to see her response.
