James Marsters has said in an interview that, when Joss Whedon let him know that Spike was gonna fall in love with Buffy in season five, he had assumed it would be one-sided - only for Whedon to correct him with a “Oh no, she’s gonna fall in love with you too.”
if i think for one single second about how spike stays in sunnydale to help raise dawn (because he said he would) and fight alongside the scoobies (because she would’ve wanted him to) even while knowing she was gone forever…. i want to start screaming and never stop
