The third clip from The Host is an exchange between Jared (Max Irons) and Ian (Jake Abel) discussing Wanda/Melanie. I know which part of the film this is from, but I think it might give away a little too much for me to explain it.
Do not ask why the embedded clip stretches the entire width of the post because I have no clue. Emebedded videos that use script are becoming a ridiculous issue with WordPress. Switch to full screen and it will look normal or go to the source (see below)
