I'm not sure if they are called cardinal values, in fact i dont think they are but in philosophy today we learned about three new values introduced to catholics via the 2nd testament, they where faith, hope and charity- which is similar to the episode title in s3 faith, hope and trick. Apparently charity means love so by missing this part out is it some kind of symbolic message saying about how buffy has no love in her life or isnt loved by scott anymore or maybe its a coedink or maybe it has another meaning, what do you think?
