I had a chance to see TFA again with my nephews on Monday and I had to explain much to their 9 and 10 year old understanding of all things from the Force universe.
In this discussion I was trying to pin down who is Rey's Father or parents as it still has not been revealed.
Here are some of the possibilities. Rank them from the most possible to least possible as you see fit.
1) Rey Skywalker
2) Rey Palpatine
3) Rey Kenobi
4) Rey [unknown Jedi lineage]
5) Rey [non-Jedi lineage]
My gut leads me to 1, 3, 4, 5, 2.
