I was having a look at the recent spoilers posted today about the episode where Bones investigates her own death is actually going to be episode 6 or 7 and it got me thinking of how Hannah is going to leave. I remember we were told that she is only going to be hanging around for six or seven episodes and coincidentally this falls around the same time that Brennan is confronted with her own morality.
So i thought what if Brennan in this episode (investigating her own death) realises that she does actually love Booth and either confronts him or makes it a bit more obvious to him. And either Booth breaks up with Hannah or Hannah sees that Booth is actually still in love with Brennan and leaves to go report somewhere else.
What does everyone else think? Is my thinking a bit too far fetched?
