While I was waiting for various pages to load, I would look over at the TV. That's when I discovered it - PROOF! of Buffy's love for Spike. She let him smoke in the house. Buffy hates smoking. Dawn stands there and complains about the second hand effects. Yet, Buffy says nothing. She looks right at him and says nothing.
Yeah, yeah, argue it was morning and she couldn't very well send him outside. Argue he'd endured torment and torture for her and she was cutting him some slack. Personally, I choose to call it love. :)
