Exactly.....imagine if we only ever ended up with a carbon copy of ourselves.
There's a massive difference between being a carbon copy of yourself, and having absolutely nothing in common that your respective life styles can't even mesh without one of you needing to change who you are. I won't go into their compatibility personality wise, because everyone will see that differently.
If you actually think the the Jade we've seen, the one that loves the beach and her family and nature more than anything would actually be happy sitting sitting alone in Melbourne, away from the sun, while Ed goes out and parties with his AFL mates then I think we must have been watching a very different person for the past 3 months.
I will argue, though, against your perspective of how Jade supposedly changed in the house. She said early on that she was a rule follower and I don't think she was ever comfortable with Tim and Drew not being so. Like I said, there was a clip of her and Drew in the halfway house where Jade was lecturing him on his behavior, telling him if he was around her more, she would keep him from getting into trouble. And the whole push to get her to fart and burp was something she was NEVER comfortable with, no matter when that happened. As for the "fun" the cool group was having, my take was that she was frustrated that the other group was deliberately causing friction through their displays of "fun". Like with the "whistles" which had happened earlier in the day, Jade knew that the others were targeting them with their fun. It was an act of passive-aggressiveness, and Jade didn't want to be part of that, even if she would have liked for all of them to have had a good time TOGETHER, but her group hadn't been invited to join in. The only way to have had the fun was to have joined in on the aggressive behavior and Jade was unwilling to do that.
For the record I do agree with (most) of this. However, the pranks, silly group wars, breaking the rules, etc wasn't what I was referring to at all. (my bad for the misunderstanding by using a bad example). More that I felt like Jade often said stuff to Ed that she thought he wanted her to say, even though it completely contradicted everything we had previously seen of her. I remember a video where Ed was telling Jade that she needed to confront Tahan on her behaviour. Jade joked saying that she wished she could just write down all of the examples and list them off during an argument. Ed said something about Tim, and Jade very awkwardly and unconvincingly said something about how his "list" would be pages and pages long. When she said it Ed smiled happily, and she immediately de-tensed like she had gotten his approval. Now from what we saw for most of the show, Jade (rightly or wrongly) quite adored Tim, and even though I think at that stage he was pissing her off with the groups thing, I also extremely doubt she thought that Tim was that bad that he had pages and pages of deficiencies. I think I only remember that video vividly because I remember thinking "oh wow".
Likewise after the Boog/Tim fight when she told Ed that she was happy for him (Ed) that the others had seen what "Tim was really like". I'm sorry, but to me from what we saw, there's no way that was Jade's own opinion of Tim, but more what she knew Ed wanted to hear. The fact that she happily slotted back in as as Tim's BFF when Ed left, after we saw with her and Drew that she could be cold to someone when she didn't like what they were doing, shows me that she didn't personally share the same issues as Ed did re Tim, but she said she did so Ed would "approve".
I think there was a lot of other issues at play here, particularly how Tim and Drew's behaviour towards Jade changed when Ed was on the scene, however there's no doubt in my mind that Jade did to a degree change her views and opinions (at least openly) for Ed. I must say though that I was impressed with her refusing to "change" when Tim, Boog and Drew were trying to get her to fart, burp, or whatever. I wish she had that same confidence with Ed though to not need his approval...which to me at least she did to a degree.
