I know I must sound like such a literature nerd but the foreshadowing, irony, symbolism, juxtaposition in BTVS and Ats are extraordinary! For example, the scene at the end of “Angel” when Angel and Buffy kiss (and her cross burns Angel) makes me melt every time! The cross is a symbol of literal burning love/passion but also serves as a symbol of barriers that come between them and pain that they have to endure. The fact that he doesn’t even flinch or complain from the burning testifies to how he would do and go through anything for her. It’s ironic too because he gave Buffy the cross, to protect herself-but it burns him. It kind of foreshadows how they can’t be close without hurting each other.
