1) Frightened/Desperate. Like when Ludwig sings him: "When the spooks have a midnight jamboree, they break it up with fiendish glee, ghosts are bad, but the one that's cursed, it's the Headless Horseman, he's the worst!"
Kokitsune always told him to not scare him, but Ludwig didn't stopped and now Faust still believes in it.

2) Happy. One of the rare occasions where Faust isn't worried, paranoic and scared.

Actually, Faust lives in London, too.
