I can't imagine any of these options, but I have to say I think the first and the second options are the most probable ones.
I can't believe that first option is so popular. That's really not who the character was.
At first I thought the same but I think it isn't that out of character.

Yeah I'm not sure why she'd want to avoid the public eye, and I find it sad that number 3 got the second highest votes.

Rachel was, when the war started a person which stood always in the center of attention because she was a really beautiful girl and then during the war she split up in to halves: The stronger side in her was addicted to the war and the fight, it was ruthless and, at some times, cruel. This was the half that liked to stand in the center of attention, but the other half was almost shy and wanted to get some peace. We saw these to sides really good in the starfish book. But it also showed during the series that at some points the 'weak' side came through but she pushed it aside because she wanted to fight the war.
But I could imagine that these weak side would come through after the war. When she'd realize that there is no more fighting I think she would calm down after a while. She realized in the war what she became and she was afraid of herself at some points but she always pushed it all aside for the sake of the war. But when it all would be over she would have to face what she became and she would have to deal with it because there would be no more excuses for her ruthlessness. And I could really imagine that she would avoid the public eye for a while to take her time to figure out who and how she is. And I think she would do this with Tobias because she gave very much of what he thought about her and also because he was the one who made her humanity show.
So I think the first option isn't that odd. But I also think it would be just a temporary option for her recovery.
