Spike opened his mouth to speak, but he couldn't find the words to say and snapped his mouth shut once again. What was it about her that made every bit of resolve, no matter how strong he thought it was, just completely dissolve the instant she spoke? He couldn't say no, not really. He knew, on some level, she may be wrong. She may be confusing desire with love, and there was a big difference between the two, but that's not what she had said. She said that she wasn't lying, she said she loved him. And whether she meant it or not was irrelevant because it was what he so desperately wanted to hear and because of that desperation, he was more inclined to believe it simply because he wanted to, regardless of whether it was true or not.
"Buffy, I..." and still, he couldn't find the words. Logically, he knew he should reject her, to remind her how they weren't right for each other, no matter how much they wanted to be. But he couldn't bring himself to do it. Instead, he reached out to take her hand in his own, pulling her with him back over to the couch, dropping down onto it and tugging her to sit down with him, sliding his arms around her.
