I think that the idea that the F1 leaves early, and is edited back into the show to follow its regular format, goes with one of the statements RS made about the editors deserving extra credit - because thats one heck of a editing job to make a former bachelorette look like she's still in the process.
It also kind of goes with the idea its hard to wrap your head around how they did it, and why really - are they so attached to the format that they can't go against it - and if Jason did, that would go with the gutsy move.
If Mel is the F1 and her HTD was shot later, and she had been previously dumped, then its not hard to imagine that her parents are really angry at J for hurting her previously and have no intention of welcoming him and the cameras into their home. Same goes for the brother.
It also fits with the notion that the timeline is all over the place. I also think its pretty jawdropping that all this would have gone on behind the scenes and yet edited to look like the process was proceeding according to 'script'.
Of course my other theory is that J and Mel were the 'scripted' couple or Fleiss backup should it not pan out with any of the other girls. Hence not seeing a love story. Only in reality they really did fall for each other and didn't know about it, each just thinking the other is acting. So they went through the motions, and then after the FRC parted ways - then J breaks down, as does Mel, having realized that they really did love each other. (Hence don't read too much into there not being a love story). Then comes a meeting after the FRC where they run into each others arms and realize that true love has indeed been found and they really DO want to be together
