Sam leaned back, feeling more than satisfied with himself. The blood was gone. He had gotten his fill. He was feeling better than ever and he knew that as soon as they dealt with this bullshit case they'd be able to get straight back to the important stuff. Tracking Lilith, making sure that she got hers. It was only a matter of time.
"Dean is waiting," he explained, sliding his hands down to her waist. "I need to get back, make sure he's all right." He started to lift her off, angling her toward the mattress beside him.
