Well, we all know MBP lies just like her Auntie Lori
I do not believe MP and AxC moved to Rexburg to "protect" LVD
I also do not believe that MP moved there to get a "fresh start"
It had everything to do with LVD being there, AxC being there and most of all, CD being there.
It was there plan to all be together, for them all to get married, and as couples, go out marching into the world to "gather" the 144,000 and to kill the zombies (ie, kill anyone that gets in their way) and wait for July 22, 2020
