Imagine if you will, coming in on the middle of Return of The Jedi in the final sequence with Luke, Vader and The Emperor and trying to explain everything in context to a 5 and 7 year old. I basically skimmed through star wars sextilogy and summed it up best i could.

Memorable Questions:

Why is Darth Vader trying to kill his son?
Why isn’t the Green Goblin (The Emperor) fighting?
Where are Bigfoot’s parents?
Where are the Fish Man’s parents?

I don’t think I did a good job clarifying anything.
