Thanks and good luck with TTT and RotK for you Lady Snickerdoodle! My sister has "a crush" on Legolas and she calls him ´the cute boy´ so I keep telling her that there'll be more Legolas soon and she remains satisfied for a while.
Personally I'd be happy to clear up the plot to the person I'm watching the film with. If she asks questions it means that she hasn't fallen asleep (like it sometimes seems in my sisters case).
