In a interview, SMG said that while Angel drinks her blood, Buffy has a huuuuge orgasm and the censorship guys didn't even understood it...It changed the candid way I was watching the scene 😀
I always read that as the subtext, just as Buffy also orgasms when she's bitten/felt up by the Master. Kate seems to climax against her will when Angel forces himself upon her in The Shroud of Rahmon (love her succumbing to his will afterwards, tenderly stroking his bite marks on her neck at the affectionate memory). Cordy has a fatal 'pleasure moment' when vampWillow and vampXander bite her in The Wish and Buffy enjoys a huge orgasm when she's raped by the Shadowman's demon in 'Get it done'.
To misquote Giles "I think that the GOT-fic (Galaxy Of Terror) subtext is rapidly becoming a text"
Now who can we ask about Buffy/Joyce and Dracula, how far Buffy and RJ went before Xander interrupted them (and what did they do when he left them alone again?), did Tania and Ivanova just have a sleepover or more and what about Ripley and the alien drone that carries her off in Joss' Alien 4?
